摘要：
A unitized electrode assembly for a fuel cell comprising an electrolyte membrane, a subgasket, and a sealing bead disposed therebetween is disclosed. The sealing bead adapted to fill a tenting region formed between the membrane and the subgasket to maximize an operating life of the electrolyte membrane by militating against wear of membrane expansion during use of the fuel cell.
