Abstract
Degradation of membranes in fuel cellsdue to dehydration by relatively dry incoming reactant gases is avoided through the use of a humidifierin the incoming reactant streams,At least one of the humidifiersis formed in a stackhaving alternating flow passageswith the former receiving reactant gases and including finstherein and the latter receiving hot coolant from the fuel cellThe finsin the flow spacesare provided with a hydrophilic coating to foster filmwise evaporation of water introduced through a nozzleThe humidifier causes the reactant gas to attain a desired dewpoint before it is provided to the membranes of the fuel cell
