Design of mobile 200 W PEM fuel cell systém

Original language description

PEM type fuel cells represents a promising device for efficient conversion of chemical energy carried by fuel into electrical energy. Absence of moving parts is the main reason for quiet operation of fuel cells. Water is a product of reaction of hydrogen with oxygen without any dangerous pollutants. Mentioned properties make mobile fuel cell stacks suitable as a power sources for e.g. mobile medical beds or medical beds in field hospitals. Other potential applications are power source for rescues or reserve power sources for firemans and medicals or speleology. All these applications require power output in a range of 80-200 W for long time and up-to 300 W for short-time operation. Therefore this project is focused to design of mobile auxiliary power unit based on PEM fuel cell at this power output. One of the most important parameter of whole housing is weight, because system has to be mobile. Safety load in the outdoor terrain is up to 15 kg. It is reason, why weight of whole system has to be lower than this limit. Weight without gas cylinder is considered, because gas cylinder can be moved separately. Housing have to protect fuel cell stack before damage by falling. Humidifier and all devices for fuel supply, air supply and energy balancing must fit in together with fuel cell stack. Air is used as a prefered oxidant, because it is not necessary to use reduction valve, gas flow controller and oxygen gas cylinder. Main problem of ambient air represents its purity. Especially in the industrial agglomerations content of various impurities in air can potentially reach high level. Some compounds like e.g. dihydrogen sulphide, carbon monoxide and selected organic compounds can poison platinum catalysts. Therefore it is necessary to include air purification by carbon filters in to the system. Selected filter have to operate with low pressure drop, because increased pressure drop leads to increasing energy demands of the system.
