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
Specifications
- 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.]
Prices
- As low as $1.4/watt [3]
- 2.5 kW costs $15k above
