Sažetak
There is a strong relationship between the efficiency and economics of Proton Exchange Membrane (PEM) fuel cells. The fuel cell efficiency is not a single number ; it is a function of power density at which the fuel cell is operating. Typically, the lowest efficiency is achieved at maximum power output. The optimum nominal efficiency that results in the least expensive electricity produced by the fuel cell is determined not only by the fuel cell performance characteristics, but also by its economics, i.e, capital cost of fuel cell and cost of hydrogen. The efficiency and economics of the fuel cells have been analyzed in various load profiles and for various development and cost scenarios. The results indicate that in the best case scenario the fuel cells can be produced at ~$100/kW, operate at 50% efficiency, and generate electricity at <$0.08/kWh if hydrogen can be supplied at $10/GJ.
