description In one embodiment, an electrochemical cell comprises: a membrane electrode assembly comprising a first active area and an opposingly positioned second active area, and a flow field support member disposed adjacent to said membrane electrode assembly. Each of the active areas comprises an electrode, and has a length to width ratio configured such that, during use of the electrochemical cell, a temperature differential measured across the shortest distance from a center of the active areas to an edge of the active areas is less than about 15° C. The flow field support member has a flow region that aligns with either the first active area or the second active area.
