    inspiringly well written and put together. Many thanks. It sounds almost too good to be true. Now I have to read the other comments first.

    The only thing I got confused with is that the platinum catalyst sits at the anode and splits the hydrogen into H+ ions and electrons, whereas the carbon-iron-cobalt catalyst sits in the cathode and completes the conversion of hydrogen and oxygen into water.

    But the Hydrogen has to be split into H+ ions and electrons first to generate the electrical flow in the circuit and to let the H+ ions through the membrane to the cathode, where then the carbon-iron-cobalt catgalyst converts the H+ ions with the electrons and the oxygen back to water again.

    So, how do you get then the H+ ions and elecrons split at the anode, if you don't have the platinum catalyst there?

    Sorry to ask, I didn't understand that part, because you still need the H+ion and electron splitting before it goes to the cathode?, or not? What did I miss?
