Pem-Brennstoffzellenstapel ohne Gasdiffusionsmedium

摘要

A fuel cell comprising an ionically conductive member with a first surface and a second surface. An anode electrode is disposed on the first surface of the ionically conductive member and a cathode electrode is disposed on the second surface of the ionically conductive member. A first electrically conductive fluid distribution element is disposed on the anode and a second electrically conductive fluid distribution element is disposed on the cathode. The first and second electrically conductive fluid distribution elements each include a plurality of alternating lands and fluid passages. The anode and the cathode are comprised of a plurality of electrochemically active regions that are disposed to essentially align with the fluid passages.
