• Fuel cell systems suitable for automotive applications Key Points & Notes operate at low temperatures (typically less than 212 ºF/100 ºC). This is an advantage in that the fuel cells re-quire little warmup time, high temperature hazards are reduced, and the thermodynamic efficiency of the electro-chemical reaction is inherently better.
