Abstract:
1. A method for forming a fuel cell, the method comprising: providing an electrode support structure comprising bacterial cellulose; placing the electrode support structure in a solution of a metal salt for a sufficient time period such that the metal salt is reduced to metallic form and the metal precipitates in or on the electrode support structure to form an electrode material; providing an electrolyte membrane; placing an anode on one side of the electrolyte membrane; and placing a cathode on an opposite side of the electrolyte membrane, wherein one of the anode and the cathode comprises the electrode material, and wherein the electrode support structure comprises hydrated bacterial cellulose, and wherein the method further comprises dehydrating the electrode support structure after the metal precipitates in or on the electrode support structure to form the electrode material, and wherein the metal salt is selected from coordination compounds including a platinum metal group complex ion, and mixtures thereof.
