FUEL CELL REACTANT FLOW FIELDS THAT MAXIMIZE PLANFORM UTILIZATION

摘要

Fuel cell reactanl gas flow fields plates (53.84, 104) have flow channels (71.98,105,106), with transverse portions 73? 100,109) some of which have more than one groove (78,79,101, 103, 111, 117,118). thereby to adjust the planform shape of he rcactnnt gas flow field.
