Title:
BIPOLAR PLATE HAVING INTEGRATED GAS-PERMEABLE MEMBRANE
Document Type and Number:
WIPO Patent Application WO2003077342
Kind Code:
A3
Abstract:
The present invention is directed to a novel anode plate forming an anode chamber of a fuel cell. The anode plate includes an anode fuel flow field (30), a substantially gas permeable membrane (36), and a channel (40) coupled to an outlet (42) positioned immediately adjacent said membrane. The channel directs gaseous effluents produced in the anode chamber out of the fuel cell via the outlet. This novel anode plate may be used in a single fuel cell, electrically and mechanically coupled to a cathode plate in a multi-fuel cell arrangement, or combined with a cathode plate producing a bi-polar plate (25) for a fuel cell stack. Alternatively, the features of the anode plate and cathode plate may be integrated into a single component, thus improving performance and limiting the size of a stack ad system implementing said stack.
