GAS DISTRIBUTOR FOR FUEL CELLS

摘要

A gas distribution member (3; 20) for a polymer membrane fuel cell comprising a highly porous, sintered material. The sintered material comprises fibers of an inorganic material. The fibers have a diameter in the range 0.5 - 50 mu , preferably 2 -25, most preferred 8 - 22 mu , and a length in the range up to 3 mm, and the porosity is in the range of more than 50 % by volume, preferably more than 90 percent by volume. Disclosed is also a fuel cell comprising said gas distribution member, and a method of making the same.
