Abstract

The light, cheap, and high-performance regenerative pump, for pumping a methanol-water fuel of a fuel cell, is adapted to the fuel. At least one of an impeller 1 of the regenerative pump and an inner wall 2 of the pump is made of polyphenylene sulfide or polyphenylene sulfide containing a filler, and a thrust clearancer formed between the pump chamber inner wall 2 and an impeller peripheral face is set so as to be assured even in a state where the impeller 1 swells.
