| Title: |
PEM FUEL CELL SYSTEM WITH A POROUS HYDROPHOBIC VENT ASSEMBLY WITH GAS FLOW BLOCKAGE PREVENTION FOR MAINTAINING SYSTEM BACK PRESSURE |
| Abstract: |
A polymer electrolyte membrane (PEM) fuel cell power plant is cooled evaporatively by a pressurized water coolant system. The coolant system utilizes a hydrophobic porous member (29) for venting gases such as fuel and/or air from a coolant water flow field in the system. Coolant water is prevented from clogging the porous member by vibrating (34) the member, either intermittently or continuously, during operation of the power plant . |
