Recent work on PEM fuel cells has demonstrated the importance of membrane mechanical properties and swelling behavior on cell performance. Mechanical properties and swelling should be considered as integral factors when developing new membranes, improving cell design, and creating models. The existence of two stable ignited states in autohumidified fuel cells and the cells' responses to dynamic conditions have revealed chemical-mechanical coupling in which the membrane's mechanical properties are changed by its water content, which in turn changes cell performance and water production. Several examples of fuel cell behavior, which mechanical properties and swelling are believed to be responsible, are presented, as well as the mechanical properties of membranes and their relevance to cell performance. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
