Hydrogen cell battery question.?

Question

once i know this question, i then can make my own calculations in my own understandings.

assume a 12oz Pepsi Can was filled only with pure hydrogen, pressure to assume no more then the surrounding air pressure. the can was insulated(glass jar, pumped clear of air {0 psi)). 1 wire connected to the can, another one is connected to aluminum foil wrapped around the jar. This should represent a basic hydrogen cell battery.

What would the voltage be, the available current be, and how long would it last?

Average numbers are ok, just want to be close...

Thanks to all in advance..

Answer 1

Again, your claim that "This should represent a basic hydrogen cell battery" just ain't so.  No current or voltage is available because there is no complete circuit.  If I understand your battery construction the jar, being an insulator, prevent the passage of electrons.  Also the hydrogen will not spontaneously combine with the air and if it were ignited there would be fire but no battery.

Answer 2

Hello,

I am more than a little confused by the structure of the hydrogen cell that you are outlining.

You have the can filled with hydrogen.   The hydrogen is inside the can.   You connect one wire to the can which is made of aluminum.   You then connect another wire to aluminum foil wrapped around the jar.

There doesn't seem to be any liquid or membrane present.   You have aluminum in the body of the can and in the aluminum foil exterior to the can.   You say there is insulation and I presume that is between the aluminum of the can and the aluminum foil.   But I don't see any way that the hydrogen will react or what it would react with.   Are you assuming air is present in the outside world and somehow that air will react with the hydrogen?

Sorry,  but I'm really confused.   Could you please clarify.
