DECREASING ELECTROLYTE LOSS IN PEM FUEL CELL

摘要

Embodiments are disciosed that relate to preventing electrolyte wicking by bipolar plates in a fuel cell system. In one example, a fuel cell system inciudes a first membrane-electrode assembly and a second membrane-electrode assembly. The fuel cell system further inciudes a bipolar plate disposed between the first membrane-electrode assembly and the second membrane-electrode assembly, the bipolar plate comprising a graphite Iayer and a surface energy adjustment Iayer.
