A flow field plate for a liquid feed fuel cell has a liquid reactant (for example, fuel) flow field comprising a plurality of horizontal parallel substantially straight channels formed on one major surface of the plate. The plate has another reactant (for example, oxidant) flow field on the other major surface of the plate. The liquid reactant channels may have an open width less than about 0.75 millimeter and/or a length to cross sectional area ratio between about 2180:1 to about 6200:1. A simple four- port configuration is employed for the inlets and outlets for the reactants. The liquid reactant can also serve as a coolant for the fuel cell.
