Abstract
A fuel cell includes an ion conducting membrane having a first side and a second side. Characteristically, the ion conducting membrane has a sufficient amount of a stabilization agent and platinum to inhibit the loss of fluoride from the ion conducting membrane when compared to an ion conducting membrane having the same construction except for the presence of cerium ions.
