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

Click For Summary
SUMMARY

This discussion focuses on the feasibility of generating electricity from hydrogen gas without purchasing a fuel cell. Participants suggest constructing a hydrogen half cell using materials such as platinum wire and sulfuric acid (0.5-1 M) as an electrolyte. The conversation highlights the challenges of energy loss during the process and the need for an oxygen half cell and a membrane or salt bridge for effective operation. Additionally, it emphasizes the volatility and containment issues associated with hydrogen gas, suggesting alternative energy sources like bioethanol and electric systems.

PREREQUISITES
  • Understanding of electrolysis for hydrogen generation
  • Knowledge of electrochemical cells and half cell construction
  • Familiarity with sulfuric acid as an electrolyte
  • Basic principles of energy conversion and storage
NEXT STEPS
  • Research the construction of hydrogen half cells and their components
  • Explore alternative electrode materials for electrochemical applications
  • Learn about the efficiency and energy loss in electrochemical systems
  • Investigate safer alternatives to hydrogen gas for energy storage
USEFUL FOR

This discussion is beneficial for experimental physicists, hobbyists interested in renewable energy, and anyone exploring alternative methods for electricity generation from hydrogen gas.

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.
