Basics

These are devices like batteries, but with oxygen and/or air as the oxydizer and a fuel (Usually gas or liquid excluding magnesium and zinc fuel cells)
More Efficient Converters Than ICE's and ECE's
Do not Produce Carbon Monoxide and other Byproducts due to lack of combustion
Do produce waste heat (amount varys based on design) (This heat can also be harvsted via something like a turbine (such as a steam one) or a Stirling Engine to improve efficiency further

40% is generally considered as the highest efficiency of hydrogen generation to usage with PEM fuel cells and electrolyzers. [1]
- Solution: distribute research worldwide and solve this by collaborative design.
PEM - 2kW/kg of weight [2]
PEM - $45/kw when manufactured on million-scale volume . [Ibid.]
Comparison to batteries - So, 145 kg total for tanks + FC system + 5 kg hydrogen, delivering an EPA estimated range of 312 miles. That compares to 540 kg for the battery pack in a Tesla Model S with a rated range of 265 miles. [Ibid.]

-*This article states that hydrogen cannot be produced cheaply. However, if we use OSE's 1 cent/kWhr cost of electricity as documented in the [[Seed Eco-Home PV System]], with alkaline electrolyzers (see [[Hydrogen Production]], the cost of returning that electricity through solar hydrogen is 5 cents per kWhr. See [[Round-Trip Electricity from Hydrogen]].
