A method is provided for patterning a solid proton conducting electrolyte ( 22, 60 ) for a micro fuel cell. The method comprises patterning a first side ( 30, 63 ) of a solid proton conducting electrolyte ( 22, 60 ) to increase the surface area, coating the patterned first side ( 22, 60 ) with an electrocatalyst ( 33, 66 ), providing a first electrical conductor ( 20 ) to the first side ( 22, 60 ), and providing a second electrical conductor ( 15, 16 ) to a second side ( 19 ) of the solid proton conducting electrolyte ( 22, 60 ) opposed to the first side ( 22, 60 ). One exemplary embodiment comprises depositing a solid proton conducting electrolyte ( 60 ) over a substrate ( 12 ), patterning the solid proton conducting electrolyte ( 60 ) to form a plurality of pedestals ( 28 ), each pedestal ( 28 ) having an anode side adjacent a anode region ( 42 ) and a cathode side adjacent a cathode region ( 43 ), coating the anode ( 42 ) and cathode ( 43 ) sides with an electrocatalyst ( 33 ), providing a first electrical conductor ( 15, 16 ) to the anode side ( 42 ); and providing a second electrical conductor ( 20 ) to the cathode side ( 43 ).
