Sažetak
The objective of this paper is to provide a general overview on optimizing a PEM fuel cell system for backup power applications based on a set of key input and design parameters such as temperature, pressure, humidification, water management, and cell voltage. Low temperature and low pressure is beneficial for system simplicity and efficiency. It is possible to relax water management and humidification requirements at low pressures by selecting low operating temperatures. Higher selected nominal cell voltage does not necessarily mean higher operating efficiency particularly if the stack is operated at partial loads most of the time. So selection of nominal cell voltage must be based collectively on factors such as cost of the stack, cost of fuel consumed, load profile and capacity factor, lifetime, etc.
