Ultra High Purity Steam in Fuel Cells
Contamination in any of the process gases (hydrogen, oxygen, and water vapor) involved in fuel cell development can lead to poisoning of the membrane catalyst and degradation of the proton exchange membrane (PEM). In addition, improper hydration of the PEM degrades performance of the fuel cell. RASIRC high temperature humidifiers allow 100% saturation of hydrogen and air up to 120ºC operation.
RASIRC RainMaker humidifiers present a new alternative to bubblers. Bubblers are limited to below boiling (100°C) and low pressure. RASIRC RainMaker humidifiers can be used with water or steam as the water source for humidification. They can be used to provide humidification at above boiling temperatures and higher pressures. This can enable PEM fuel cells to operate more efficiently.
