Simple Water Fuel That question answered alone would be helpful, but if anyone could point me toward an FAQ or some such on the science of a hydrogen generator, that would be extremely appreciated.
Thank you.
Chosen Answer:
If hydrogen is generated by electrolysis, one O2 is generated for every two H2 molecules. But that would never be the basis of a hydrogen ecomony – to use electricity to generate hydrogen. Electricity is always more valuable than hydrogen.
Usually, you’d let the oxygen go, since we can get oxygen anywhere we need it. If you then
In the shift-gas reaction, a more common way to generate large quantities of hydrogen, no oxygen is generated.
