Document Type and Number:
WIPO Patent Application WO2001097311
Kind Code:
A3
Abstract:
A fuel cell has a proton exchange membrane. In known manner, the fuel 12 cell includes inlets and outlets for flow of an oxidant and for flow of a fuel gas, commonly hydrogen. To deal with the issue of humidification, the invention provides a recirculation conduit including a pump 54 connected between the anode inlet 44 and the anode outlet 46. A water separator 50 is provided in the recirculation conduit, for separating water from fuel gas exiting the anode. A main fuel inlet 48 is connected to the recirculation conduit, for supply of fuel. A branch conduit can be provided, to enable purge cycles and other options to be provided.
