About HHO Fuel Cell，There are many fun projects ideas out there for electronic enthusiasts, and some may even require a source of energy to work. These include projects like automobiles, some high-grade mechanical toys, and even drones.
So, if you’re looking for a source of electricity for such projects, you’re in the right place.
The hydrogen fuel cell is your go-to.
Though it has its disadvantages, it’s still one of the best sources of electricity.
So, in this article, we’ll tell you everything you need to know about hydrogen fuel cells and how to make a simple hydrogen fuel cell circuit.
Buckle up, and let’s learn!
What is a Fuel Cell?
A fuel cell uses hydrogen chemical energy or other fuels to produce clean and efficient energy. Also, fuel cells have a wide variety of potential applications. Plus, they can utilize a wide range of fuels and feedstock and power systems as large as utility power stations or small as laptop computers.
Here’s another view. Fuel cells are devices that use electrochemical reactions of hydrogen and oxygen to create electricity, water, and heat—not combustion. Today, fuel cells have a large variety of uses like powering homes and businesses, keeping critical facilities like hospitals, data centers, and essential stores running.
Also, fuel cells have advantages over traditional combustion technologies, including lower emissions and greater emissions.
Here’s the best part.
Since HHO fuel cells only emit water and heat, there are no dangerous pollutant emissions, like carbon dioxide, released into the atmosphere. Not only are fuel cells safe, but they are usually silent during operation. Why? Because they have fewer moving parts than combustion technologies.
Some kinds of fuel cells can use hydrocarbon fuels like biogas, methanol, natural gas, etc., because they use chemistry to generate electricity—rather than combustion. Additionally, fuel cells offer higher efficiencies than what you’ll get from traditional energy production methods like internal combustion engines or steam turbines.
You can get even more efficiency by combining the fuel cell with a heat and power system circuit that utilizes the waste heat for cooling or heating applications.
Moreover, fuel cells are scalable. In other words, you can join individual fuel cells with another to create stacks. Plus, you can combine these stacks into larger systems. Fuel cell systems have different sizes and power, from multi-megawatt installations to replacements for electric vehicles.
How Does Hydrogen Fuel Work?
As I mentioned earlier, fuel cells generate electricity through a chemical reaction. However, fuel cells achieve this through electrodes and an electrolyte membrane. Every fuel cell has two electrodes, a positive cathode and a negative anode.
Also, the electrochemical reaction that generates electricity happens at these electrodes, with an electrolyte membrane moving charged particles between the electrodes. Plus, there is a catalyst present that speeds up the reactions.
Additionally, hydrogen works as the primary source of fuel in an HHO fuel cell. But, oxygen is also required for the cell to work. Thus, we can summarize how fuel cells work into four processes:
- First, the hydrogen atoms enter through the anode while oxygen enters through the cathode
- Next, the anode separates the hydrogen atoms into protons and electrons
- The positively charged protons move to the cathode through the electrolyte membrane. The electrons, on the other hand, are negatively charged and moved through a different route and through the circuit to create electricity.
- After the electrons pass through the circuit and electrolyte membrane, they meet the protons at the cathode and combine with oxygen to create water and heat as by-products.
Note: the oxygen atom isn’t essential in this process.
Plus, single fuel cells don’t create large amounts of electricity. So, you can arrange them into stacks to generate enough power for your intended purpose.
Furthermore, fuel cells are similar to batteries, but contrary to batteries, fuel cells don’t need recharging or run down. You can continuously generate electricity as long as you supply the fuel source (hydrogen or other hydrocarbon fuels), making it one of the best renewable energy sources out there.
How to Make HHO Fuel Cell Circuit
Here, we will learn how to make an easy HHO fuel cell circuit. According to a theory hypothesized by Stanley Meyer, there are ways for generating HHO gas more efficiently. The goal here is to create as much HHO gas as possible without using more power for production. Also, igniting the gas and using the results to make the desired mechanical action. So, you can break water into hydrogen gas in large quantities while using minimal current with the following simple circuit.
Using a CDI transformer is your most straightforward option for generating high voltages, as you can see in the above diagram. So, this is a CDI circuit that helps develop HHO gas with maximum efficiency.
We divided this circuit into three primary stages: the IC astable, step-up transformer, and capacitive discharge stages using the CGI transformer from an automobile.
When you switch on the power, the IC 555 starts oscillating and generates a corresponding frequency at pin 3. Also, it helps switch the connected transistor. This rigged transistor (with a step-up transformer) starts transferring power into the primary winding at an applied rate. The primary winding is correctly stepped up to 220v—across the secondary winding of the transformer.
This stepped-up 220V voltage feeds the CDI’s voltage. However, the circuit implements it first by storing it in a capacitor. So, once the voltage of the capacitor touches the set threshold limit, it uses a switching SCR circuit to fire the voltage across the primary winding of the CDI.
The CDI coil then treats and boosts the 220V to a vast 20,000 volts or above and moves it out through the high tension cable.
Also, the 100k pot connected to the IC 555 regulates the timing of the capacitor’s firing, and it also determines how much current the output of the CDI transformer will receive.
Finally, the CDI coil’s output will transfer to the water for the electrolysis process and HHO generation.
Here’s a simple setup for the process discussed above:
In the diagram above, we can see two vessels (plastic vessels). The ship on the left contains two hollow parallel stainless tubes and two stainless steel rods inside the hollow tube. So, follow these steps to set up the diagram above:
First, connect the two tubes and rods electrically. But, ensure the tubes and rods don’t touch each other. These rods and tubes will serve as electrodes placed inside the water-filled vessel.
Take the lid of the first vessel and install two terminals for integrating the electrodes to the high voltage generator circuit. When you switch on this high voltage from the course, it rapidly electrolyzes the water between the internal walls of the tubes and the rods. Then, it converts it into HHO gas.
Set up your second vessel (collector’s vessel) and fill it with water. It’s important because the water allows you to bubble out the gas into the chamber when it’s sucked out and used by the external combustion system. Also, it prevents accidental fire or explosions within the collector’s vessel.
Install a connecting tube to connect the vessel with the electrodes to the other water-filled ship on the right. This tube allows the flow of electrons between the two boats.
Test the setup to see if it works. With this, you should generate high amounts of efficient HHO gas and produce an output that’s 200 times higher than the power you consumed to make it happen.
Advantages of Fuel Cell Technology
Hydrogen fuel cell technology has many pros that make it one of the best options for power generation. So, here are some of the benefits of using fuel cell technology:
- Low/zero emissions
- Fuel efficiency
- Energy security
- Quiet operation
- Scalability (fuel cell stacks)
- High efficiencies
Despite having many pros and various applications, the HHO fuel cell technology has a few demerits. So, here are some of the drawbacks of using fuel cell technology.
- High Cost
Though hydrogen fuel cells are cheaper to maintain, it’s expensive to get one. The cost of fuel cells is so high because the costly platinum catalyst is one of the major components. However, work is underway to find a non-platinum solution.
- it takes a lot of time to extract hydrogen for fuel cell use
- the flammable nature of hydrogen poses a serious problem to safety
The Bottom Line
There is a wide range of fuel cell applications, from supplying power to moving vehicles like cars, trains, and buses. Fuel cells act as a source of electrical energy for various industrial, residential, and commercial applications.
There are also different types of fuel cells with other fuel cell performance. These types include alkaline fuel cells, solid oxide fuel cells, reversible fuel cells, and others.
Also, since hydrogen fuel cells use hydrogen and oxygen chemical reactions, there is no need for liquid fuels like diesel fuel or fossil fuels to create electrical power. Plus, it doesn’t require solar power either.
Additionally, the fuel cell power is a portable power source. One fuel cell weighs less than 10kg but produces up to 5Kw of power.
