First claim
Opening claim text (preview).
1 - 8 . (canceled) 9 . A fuel cell comprising an anode, a cathode and an electrolyte, wherein the anode comprises an electrode catalyst comprising an electrically conductive material carrying a metal or a metal oxide, and having an electrical conductivity at 30° C. of 1×10 −13 Scm −1 or more; said metal is one or more transition metals and said metal oxide is an oxide of a transition metal; and said electrolyte has proton conductivity; and wherein an α-hydroxycarboxylic acid contacts the anode to generate protons and electrons; the protons move in the electrolyte and reach the cathode; and the protons and oxygen are reacted on the cathode to produce water. 10 . An energy recovery system for recovering surplus electric power energy, the system comprising: a container for storing an α-keto carboxylic acids; a container for storing an α-hydroxycarboxylic acid; and a means for electrochemically oxidizing said α-hydroxycarboxylic acid to produce said α-hydroxycarboxylic acid and generating electric power, wherein said means comprise an anode; wherein the anode comprises an electrode catalyst comprising an electrically conductive material carrying a metal or a metal oxide, and having an electrical conductivity at 30° C. of 1×10 −13 Scm −1 or more; said metal is one or more transition metals and said metal oxide is an oxide of a transition metal’ and wherein the α-hydroxycarboxylic acid contacts the anode to generate protons and electrons. 11 . A power generation method for generating electric power using the fuel cell of claim 9 .
