how pem fuel cells are made
the different gases in ambient air are unreactive in a hydrogen gasoline cellular. The earth's air contains: seventy 8% nitrogen (very nearly unreactive in all situations) 20.ninety 5% oxygen (organic oxidant) 0.ninety 3% argon (unreactive) 0.04% carbon dioxide 0.08% mix of alternative hint gases So the oxygen content fabric in air is approximately 200 circumstances extra suitable than the different gasoline that could react with the hydrogen. additionally, being a organic oxidant, it is the popular gasoline for the hydrogen ion to react with.
If you mean protein exchange membrane fuel cells, then my source might help you get started.
