    Abstract

    The Ni60Nb15Ti15Zr10 glassy alloy was developed as a separator material for a proton exchange membrane fuel cell (PEMFC). The corrosion rate of the glassy alloy in sulfuric acid was approximately 3 digits lower than SUS316L. A precise groove forming of the glassy alloy can be achieved by hot-pressing in the supercooled liquid state. The result of the power generation test of the single cell assembled with the groove-formed glassy alloy sheets revealed that sufficient power was generated. Moreover, the deterioration of the morphology of the glassy separator could hardly be recognized even after the durability test for 350 h.
