Abstract
A fuel cell including at least one of a hydrophilic interlayer and a flow field treated to impart hydrophilic properties is disclosed, wherein the hydrophilic interlayer and the treated flow field militate against water accumulation in ultrathin electrodes of the fuel cell, particularly for cool-start operating conditions (i.e. about 0° C. to about 60° C.).
