The potentialities of a membrane passive humidifier and its interaction with two different air supply devices were examined for application on a PEFC (polymeric electrolyte fuel cell) system to be used in vehicles. A rotary vane compressor was compared to a side channel blower with respect to their capability to assure the correct working of the membrane humidifier in different load conditions. The results obtained on a 12 kW stack evidenced that the higher working pressures of the rotary vane compressor permitted improvements in individual cell performance, and determined the possibility to reduce the energy requirements of humidification devices.

Abstract
The potentialities of a membrane passive humidifier and its interaction with two different air supply devices were examined for application on a PEFC (polymeric electrolyte fuel cell) system to be used in vehicles. A rotary vane compressor was compared to a side channel blower with respect to their capability to assure the correct working of the membrane humidifier in different load conditions. The results obtained on a 12 kW stack evidenced that the higher working pressures of the rotary vane compressor permitted improvements in individual cell performance, and determined the possibility to reduce the energy requirements of humidification devices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
