description	A seal material having improved sealing characteristics and useful in high temperature, corrosive environments, particularly fuel cells is disclosed. The material comprises an acid resistant, high temperature stable fluorinated elastomer and a blowing agent which activate at a temperature within the range of curing temperatures of the elastomer. Improved sealing characteristics due to volume expansion of the seal material applied and activated within the fuel cell were observed. The process of activating the seal material at the operating temperature of the fuel cell is also disclosed. The invention also discloses the process of using the seal material within a fuel cell.
