 Hydrogen Water Fuel Cell Results
Using Kanarev`s Data
Modern Electrolyzers consume 4 .0kWh per cubic meter of this gas.
When one cubic mete of hydrogen is burnt,3.55 kwh of energy is released.

One litre of hydrogen weighs 0.09 gram:One litre of oxygen weighs 1.47 g. It means that
it is possible to produce 111.11/.09=1234.44 liters of hydrogen and 888.89/1.47=604.69
litres of oxygen from one litre of water.One gram of water contains 1.23 litres of hydrogen
Energy consumption for the production of 1000 litres of hydrogen is 4 kWh andfor one
litre 4Wh .It is possible to produce 1.23 litres of hydrogen from one gram of water,1.23x4
=4.94Wh is spent for hydrogen production from one gram of water.

Duration of test in min. = 60
RMS Voltage V = 7.5
Ampmeter I, amperes = 0.06
Power P,watts hour (P=VxIxmin/60 0.45
Mass of wfc in grams = 106.9
Mass change in grams m = 0.4
Evaporating water mass me, = 0.04
Mass of water split into gasses, m-me = 0.36
Existing energy consumption Wh/g water = 4.94
Released hydrogen quantity 0.36x1.23x0.09= 0.03985
Energy content of produced hydrogen (W=0.03985x142/3.6)= 1.57186
Energy Efficency (Wx100/P) % )= 349 %


Energy Efficency of this WFC is 349 % or overunity

how do you get a cubic meter of a gas? i'm sure that the area that a gas takes up is relative to the temperature that it is...
