Seals for fuel cells and fuel cell stacks |
| abstract |
A fuel cell stack assembly having a plurality of plates with grooves for accommodating gaskets to provide seals between individual fuel cell plates in the fuel cell stack assembly in order to prevent leakage of gases and liquids required for operation of the fuel cell stack assembly is presented. The grooves in each fuel cell plate in the fuel cell stack assembly comprise a circular or an elliptical profile and a unitary seal formed of a sealing material between each fuel cell plate in the fuel cell stack assembly having a profile corresponding to the profile of the grooves in each fuel cell plate. The sealing material contains polydiorganosiloxane, reinforcing filler, an oxide or hydroxide of an alkaline metal, an organohydrogensiloxane and a platinum type metal catalyst. |
