What are the advantages and disadvantages of fuel cells relative to lithium-ion batteries?
Since the fuel cell can convert the chemical energy of the fuel directly into electrical energy, it does not change the energy form of the boiler, the steam turbine, and the generator as the usual thermal power generator can avoid the loss of the intermediate conversion and achieve a high power generation effectiveness.
Fuel cell cost is high: the cost of the vehicle PEMFC in the proton exchange membrane (USD300 / m2) about 35% of the cost; platinum catalyst about 40%, both are valuable materials.
Fuel cell involves chemical thermodynamics, electrochemistry, electrocatalysis, materials science, power system and automatic control and other disciplines of the theory, with high power generation efficiency, less environmental pollution and so on.
