part of the heat energy generated by combusting the H2 will be lost as waste heat,

It would probably be better to use the same catalyst and convert the Hydrogen and Oxygen back into electricity, and run your vehicle on that. You could all or most of the same components already in use for Hybrid and all electric vehicles. In fact it would be much like a hybrid, except the electricity would be generated by the fuel cell, rather than an internal combustion engine turning a generator. I suspect you'd still need a battery, because the peak output of the fuel cell wouldn't be high enough for acceleration or hill climbing at highway/freeway speeds. But I could be wrong about that, since I don't know all the details of fuel cell dynamics.

—The system is still a net loss, or rather electricity is converted to heat in the process.—

My assumption was that for this to be viable, whatever burns the hydrogen and Oxygen, effectively re-uniting them into water, would power a generator to supply the electricity for the chemical reaction, and it would need to require less energy to produce the electricity than the amount of energy produced by the combustion of the hydrogen and oxygen.

IOW, for this to matter, it requires water and electricity to be applied to the catalyst. The result would be hydrogen and oxygen. The two would then be burned, as gasoline and oxygen are burned in an internal combustion engine. The power would be sufficient to turn a driveshaft, powering a vehicle, lawn mower, hydrolic pump or other tool, as well as a generator that produces at least as much electricity as it took to enable the splitting of the water molecule in the first place.

Otherwise I assume it would be pretty useless, taking in more power than it produces.

Energy is neither created nor destroyed. It simply changes forms...........

Useless in the sense you describe.

How is it possible for Brookhaven to put out a physics article about a water-splitting catalyst that doesn't once mention catalyst energy reduction numbers? No percentages? No yields? Nothing?

Bah. I HATE this dumbing down crap.

Well, they said it was ‘close to platinum’ so they figured everybody already knows...............
