Abstract
According to an example embodiment, a method of making a phosphoric acid fuel cell component includes situating at least one polymer film layer against a permeable component layer. The polymer film layer comprises a polymer that is chemically resistant to phosphoric acid. The polymer film layer is melted. The permeable component layer is impregnated with the melted polymer to thereby establish a region on the component layer that is impermeable to phosphoric acid. The impregnated region also provides a seal against reactant leakage from the component.
