Fuel cell reactant flow fields that maximize planform utilization

Fuel cell reactant gas flow field 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, 112; 117, 118 ), thereby to adjust the planform shape of the reactant gas flow field.
