Homemade Hydrogen fuel cell?

How, if possible, can you make a Hydrogen fuel cell from materials you can find around the house? And no, I do not mean something that produces hydrogen, I mean something that combines it with Oxygen to produce Water and Electricity, like the kind in Hydrogen cars. I have looked everywhere and all I can find is how to produce hydrogen and where to buy Hydrogen fuel cells, nothing about how to make them.

Answer:

This could be fun. Hydrogen fuel is water that has had electrical current run through it. So what you do would have to be fake, a representation. I would use a small fish tank empty but use the thing that makes bubbles. I would put a glow light that shines through water. This would represent the process of making hydrogen (electrifing water). A toy tanker truck that hauls to a toy hydrogen station and a toy car to fill up. Yep, fun.
Practical fuel cells can be pretty high-tech.
