THE SCHATZ SOLAR HYDROGEN PROJECT
The Schatz Solar Hydrogen Project is a full-time, automated, stand-alone energy system that demonstrates that hydrogen can be used to store solar energy. It powers the air compressor that aerates the aquaria at Humboldt State University's Telonicher Marine Laboratory in Trinidad, California. The system uses energy from the sun to power the compressor directly and to produce hydrogen that powers the compressor when the sun is not available. The end result is that the fish enjoy solar-powered air bubbles twenty-four hours a day.
In the solar hydrogen cycle, solar energy provides the electricity to remove hydrogen from ordinary water by the process of electrolysis. The hydrogen can then be stored or transported. When hydrogen is recombined with oxygen, usable energy results. No resources are consumed and the only byproduct is pure water. In this cycle hydrogen is an energy carrier; it allows us to store and transport solar energy in large quantities.

For the plans provided by Snap, frequency is the key - heat really has no real effect...as for standard fuels cells, well it may be the case.
As for the PEM Fuel cell, hydrogen and oxygen still have to be produced.

Problem with electrolysis, it takes lot's of energy to produce a sizable amount of hydorgen and oxygen gas from water. The rate which this occurs is slow too. We ran quite a bit of current through water in a specialy designed flask, we got nothing but small bubbles forming on the cathode and anode. Heating the water would be a hazard for people manufacturing the hydrogen/oxygen (it's dangerous work), solar energy wouldn't be enough to keep up with demand in the future if this gets implimented. Vast areas of land would have to be cleared to create a large enough solar collection area(s) to generate the energy or heat needed, envirometal effects would be devistating. I don't see a promising future for this kind of water fuel system, it will produce alot of pollution from coal, oil, and nuclear sources, and large areas of land would have to be dedicated to solar arrays to generate enough energy to make sizable quanties of hydrogen. For every positive you can think of there always will be a negative. Hydrogen fuel looks good now, it being clean and all, but what are the negatives.
The energy required to produce hydrogen by electrolysis is about 32.9 kW-hr/kg. A kilogram is about 2.2 lb. For 1 mole (2 g) of hydrogen the energy is about 0.0660 kW-hr / mole.
