    PEM fuel cell designs with turbine and Stirling engine recovery

    Here are the descriptions of two of my designs. ET1: Turbine and Electrolysis System The Turbine: I have used the water vapour exhaust of a PEM fuel cell to run a turbine to make electricity. After the water vapour has passed through the turbine it goes to electrolysis system. The...

    Why Can't Fuel Cells Simply Use Water to Generate Hydrogen?

    [FONT=Arial]I was wondering if you could recommend an article that would explain a concept to me. That is: the drawback of fuel cells, reportedly, is that hydrogen is not readily available. However, I am wondering why it is that if the original idea of fuel cells came from reversing the...

    Design for a Hydrogen Fuel Cell

    Hey guys anyone have an idea for a hydrogen fuel cell. I was thinking about one in which a battery first is used to split water into h2 and o2 using electrolysis. And then the components can be combined to produce energy. Anyone have any other ideas or links? Thanks.

    Why do electrons move from anode to cathode in a fuel cell?

    From what I understand about fuel cells, they generate power by influencing electrons to move themselves around an ion-conducting material to get to the other side. While the electrons make there way from one side to the other, they supply DC in the middle of there journey. But I am not quite...

    Can a fuel cell rust if water is left inside it?

    [SOLVED] Can my fuel cell rust I just bought the THames and Kosmos Fuel Cell car and experiment kit. I used it to day and their is still a small amount of water left in the fuel cell. will this make it rust. here's a link to the car http://www.thamesandkosmos.com/store/fuelcell1.html...
