Can I turn hydrogen gas into electricity without purchasing a fuel cell?

AI Thread Summary
The discussion centers on the challenges and considerations of using hydrogen as an electricity source after generating it through electrolysis. The initial focus is on the practical steps to convert hydrogen and oxygen gases into electricity without purchasing a fuel cell. It is noted that hydrogen serves more as an energy storage medium rather than a direct energy source, similar to copper wire. The conversation highlights the importance of electrode materials, suggesting platinum wire for constructing a hydrogen half cell in an acidic solution, while acknowledging the potential issues with energy loss and low current output. The need for an oxygen half cell and a membrane or salt bridge is also mentioned. Additionally, there are cautions regarding the volatility and containment difficulties of hydrogen, suggesting that alternative energy sources, such as bioethanol or electric systems, may be more viable due to the inherent challenges of working with hydrogen fuel cells.

I would like to start experimenting with hydrogen as an electricity source, but I haven't been able to find any good resources for steps after the hydrogen generation. I've made some prototypes of small-scale hydrogen generation using electrolysis, so now I basically have two bags, one filled with hydrogen and the other one with oxygen. My question is now how do I go about taking these two gases and turning them into electricity. I'm looking for a feasible option that doesn't require just purchasing a fuel cell, rather, making my own.

Hi drew, :welcome:

Re-think: hydrogen is just as much an energy source as copper wire ...

The way to 'make' electricity is to not use it to make hydrogen.

It is more of a science experiment/test, just too see how it works and such.
 
But to test it as a source you have to take it from somewhere first. Yes, there is a loss of energy in the process.

Hydrogen half cell comes to mind as part of a possible setup. You will have problems finding good electrode material though.

Lets say I can obtain the electrode material (platinum wire or whatever is necessary), any thoughts on constructing a half cell?
 
Wire in the acidic solution (around 0.5-1 M sulfuric acid would be my first choice), gas bubbled through the solution. You won't get high currents, and you will lose plenty of hydrogen (unless you can make it a closed system, with the gas circulating), but it should already work. You will need an oxygen half cell as well, and some kind of membrane (or a salt bridge).
 
Hydrogen is a energy storage medium, like a battery. Not an energy cell.

Considering hydrogen gas is hard to work with, volatile, explosive, hard to contain without leakage, consider using something else.
There's a reason technology develops towards bio ethanol/propanol and electric, not hydrogen gas fuel cells.
