1. A method of generating hydrogen gas, comprising: providing an electrolysis cell which comprises a polymer electrolyte membrane disposed between an anode and a cathode; circulating an organic fuel and water around said anode, wherein the organic fuel is selected from the group consisting of dimethoxymethane, trimethoxymethane, trioxane, formaldehyde, and formic acid; supplying a DC electrical current to said anode and cathode; inducing electro-oxidation of said organic fuel at said anode to produce protons; and initiating electro-reduction of said protons at said cathode to produce hydrogen. 2. A method as in claim 1, wherein said inducing electro-oxidation of said organic fuel is accomplished by applying an anode catalyst on said anode, said anode catalyst selected from the group consisting of a platinum, a ruthenium, a platinum-ruthenium alloy, and a platinum-ruthenium particulate mixture. 3. The method as in claim 2, wherein said anode catalyst is applied on said anode with a loading approximately from 0.1 mg/cm2to 4.0 mg/cm2. 4. A method as in claim 1, wherein said inducing electro-reduction of said protons is accompanied by applying a cathode catalyst on said cathode which includes platinum.
