Abstract
A membrane electrode assembly for use in a fuel cell includes an anode electrode, a proton exchange membrane, an anion exchange membrane and a cathode electrode. The anode electrode includes a first catalyst. The first catalyst separates a reducing agent into a plurality of positively charged ions and negative charges. The proton exchange membrane is configured to favor transport of positively charged ions therethrough and is also configured to inhibit transport of negatively charged particles therethrough. The anion exchange membrane is configured to favor transport of negatively charged ions therethrough and is also configured to inhibit transport of positively charged ions therethrough. The cathode electrode includes a second catalyst and is disposed adjacent to a second side of the anion exchange membrane. The second catalyst reacts electrons with the at least one oxidizing agent so as to generate+reduced species.
