Precisely-structured electrochemical cell electrode and method of making same
Patent
·
OSTI ID:7361821
An electrochemical cell electrode is described comprising a first face adapted to be exposed to an electrolyte and a second face adapted to be exposed to a gaseous fuel cell reactant, a plurality of porous hydrophobic regions extending between said first and second faces and a plurality of porous hydrophilic catalyst-containing regions extending between said first and second surfaces. The hydrophobic and hydrophilic regions are disposed alternately with each other with the interfaces between said regions being contiguous and clearly defined across the thickness of the electrode from said first surface to said second surface.
