Abstract:
1. A fuel cell comprising: an electrolyte membrane comprising a membrane support structure comprising bacterial cellulose; an anode disposed on one side of the electrolyte membrane; and a cathode disposed on an opposite side of the electrolyte membrane, wherein at least one of the anode and the cathode comprises an electrode support structure comprising bacterial cellulose, and a metal catalyst disposed in or on the electrode support structure, the metal catalyst being disposed in or on the electrode support structure by 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 catalyst precipitates in or on the electrode support structure, and wherein each anode or cathode comprising an electrode support structure comprising bacterial cellulose is held together to the electrolyte membrane by hydrogen bonds.
