Patent attributes
The present invention is related to fuel cells and fuel cell cathodes, especially for fuel cells using hydrogen peroxide, oxygen or air as oxidant. A supported electrocatalyst (204) or unsupported metal black catalyst (206) of cathodes according to an embodiment of the present invention is bonded to a current collector (200) by an intrinsically electron conducting adhesive (202). The surface of the electrocatalyst layer is coated by an ion-conducting ionomer layer (210). According to an embodiment of the invention these fuel cells use cathodes that employ ruthenium alloys RuMeIMeII such as ruthenium-palladium-iridium alloys or quaternary ruthenium-rhenium alloys RuMeIMeIIRe such as ruthenium-palladium-iridium-rhenium alloys as electrocatalyst (206) for hydrogen peroxide fuel cells. Other embodiments are described and shown.
