Development of the mobile APU system based on the PEM fuel cell stack

Original language description

PEM type fuel cells represent promising devices for efficient conversion of chemical energy carried by fuel into electrical energy. They possess several important advantages as high efficiency, high flexibility or high process intensity and absence of moving parts. Absence of moving parts is main reason, why fuel cells are silent in comparison to combustion engines. Only ventilators ensuring air supply or hydrogen recirculation represent typically in fact a source of noise in this device. Beside electricity main products of PEM fuel cells are only pure water and heat. Due to this reasons, the fuel cell stacks can be successfully used as portable power sources for mobile medical beds or in field hospitals. Other potential applications represent power source for speleologist, rescues operations in old mines and in outlying areas, or reserve power source for firefighters and police. Mobile PEM fuel cell unit can also be used as temporary power source for telecommunication transmitters or meteorological stations. All these applications require construction of suitable mobile system for PEM fuel cell stacks. Power consumption of lights, walkie-talkie, cellular phones, GPS, notebooks, rescue devices for medicine dramatically decreased in last decades, but their importance, number of installations and demands on their performance is still growing. Typical energy consumption of modern medical bed or rescue unit in long-time service falls into the range of 80 - 200W, or up-to 300W in peak consumption. Therefore the typical PEM fuel cell unit for mobile application has to contain stack of performance 100 -200W. Air is used as oxidant to reduce weight and size of the system, as the oxygen gas cylinder is in such a case avoidable.
