Publication number: 20060147785Abstract: A fuel cell is comprised of a pair of bipolar plates and a membrane electrode assembly sandwiched between the bipolar plates disposed in parallel. A hard stopper is disposed between the two bipolar plates to prevent the two bipolar plates from over-squeezing the membrane electrode assembly. The stopper can be formed by thickening the bipolar plates or in an appropriate region on the membrane electrode assembly. The gap between the components of the fuel cell is controlled within an appropriate range, instead of too narrow or too wide. This helps improving the performance of the fuel cell.Type: ApplicationFiled: November 9, 2005Publication date: July 6, 2006Inventors: Shu-Ching Chiang, Jar-Lu Huang, Yi-Yie Yan, Hsin-Sen Chu
