NOVELTY - A fuel cell (100) comprises anode (102), cathode (104), and electrolyte (106) disposed between the anode and the cathode, where at least one of the anode and the cathode includes an electro-catalyst dispersed on a hybrid support, the hybrid support includes a first, carbon-based support and a second support different from the first, carbon-based support, and a weight percentage of the second support is at least 10% relative to a combined weight of the first, carbon-based support and the second support.    USE - As fuel cell e.g. proton exchange membrane fuel cells, alkaline fuel cells, phosphoric acid fuel cells, solid oxide fuel cells, molten carbonate fuel cells, direct methanol fuel cells, zinc air fuel cells, protonic ceramic fuel cells, biological fuel cells, direct borohydride fuel cells, metal hydride fuel cells, formic acid fuel cells, and direct ethanol fuel cells, for generating electricity.    ADVANTAGE - The fuel cell employs a hybrid support including at least two different types of support materials, which as a combination can dramatically and synergistically increase a lifetime of an electro-catalyst as well as its activity.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) electrode for a fuel cell comprising hybrid support, and an electro-catalyst dispersed on the hybrid support, where the hybrid support includes a primary support of reduced graphene oxide and a secondary support of a carbon-based material different from reduced graphene oxide, and a weight ratio of the secondary support to the primary support is 3:7-7:3; and    (2) manufacturing an electrode for fuel cell involving combining an electro-catalyst with primary support to form an electro-catalyst- loaded primary support, and combining the electro-catalyst-loaded primary support with a secondary support to form composite of the electro-catalyst, the primary support, and the secondary support, where one of the primary support and the secondary support includes reduced graphene oxide, and another one of the primary support and the secondary support includes a support material different from reduced graphene oxide.
