ABSTRACT:
Treated porous flow field members are used to support membranes in electrochemical cells and to enhance fluid flow to and from the membrane. The treated porous includes a support material having at least a portion thereof treated with a quantity of hydrophobic polymer, a quantity of hydrophilic polymer, or a quantity of a mixture of a hydrophobic polymer and a hydrophilic polymer. Depending on the type of treatment and the placement of the polymer-treated porous support, various fluid flow enhancements are attained.
