Hydrogen energy > Electrolysis of H20 and Hydrogen on demand generation

Here is a way to make hydrogen gas out of water and its new to me!A liquid metal alloy called"Galinstan" is allowed to soak onto the surface
of an aluminum electrode or object,dropped into plain water and bubbles off hydrogen until the metal is all used up.Thus opens up the way to use of fuel cells. http://nanohub.org/topics/SplittingWaterUsingAluminum triffid
This is the first place I heard about it. http://www.instructables.com/id/SODA-CAN-HYDROGEN-GENERATOR/
a u-tube video on it http://www.youtube.com/watch?v=dhroR7oELwA&feature=channel

Its only 4% efficient.And uses water as an electrolyte.And platinum coated nichrome wire.
http://sci-toys.com/scitoys/scitoys/echem/fuel_cell/fuel_cell.html they sell pt coated wire at $14.31 a foot.In their "hot stuff" catagory.

These are not fuel cells.
The term "fuel cell" arrives from NASA's work on space craft where there is a requirement
to GENERATE ELECTRICITY from a source of compressed hydrogen gas.
i.e. completely the opposite.

Well Paul-R,You are right that two wires in a glass of water is not a fuel cell,but it might show the principle?Did you already know about Galinstan?Its been around a while I guess?Yesterday was the first time I learned it could be used to make hydrogen on demand.That Galinstan could be used to make that pressurized hydrogen?triffid
triffid:
test

I read somewhere that that 5 psi of hydrogen is fed into a real hydrogen fuel cell.
