Methods of making oxygen distribution members for fuel cells |
摘要 |
A water-pervious oxygen distribution member for a hydrogen fuel cell is made by a method comprising chemical surface treatment of a carbonaceous member to impart hydrophilicity while retaining mechanical strength and electrical properties. The oxygen-distribution member produced provides unobstructed passageways for oxygen to access the cathode while permitting water to egress through porosity of the member.
