NOVELTY - A membrane electrode assembly (102) comprises an anode electrode (110) including a first catalyst, and configured to receive a reducing agent; a cation exchange membrane (120) configured to favor transport of positively charged ions and to inhibit transport of negatively charged particles; an anion exchange membrane (130) configured to favor transport of negatively charged ions; and a cathode electrode (140) configured to receive an oxidizing agent(s).    USE - A membrane electrode assembly for use in an electrochemical device including fuel cell (100) for generating electrical energy from a reducing agent (claimed).    ADVANTAGE - The membrane electrode assembly provides a fuel cell which is self hydrating without requiring complex water management schemes and that does not produce large amounts of undesirable compounds.    DETAILED DESCRIPTION - A membrane electrode assembly (102) comprises:    (A) an anode electrode (110) including a first catalyst, a first anode surface, and an opposite second anode surface, and configured to receive a reducing agent along the first anode surface, and the first catalyst configured to separate the reducing agent into positively charged ions and negative charges;    (B) a cation exchange membrane (120) having a first cation exchange membrane side adjacent to the second anode surface, and an opposite second cation exchange membrane side, and configured to favor transport of positively charged ions and to inhibit transport of negatively charged particles;    (C) an anion exchange membrane (130) having a first anion exchange membrane side, and an opposite second anion exchange membrane side, and configured to favor transport of negatively charged ions and to inhibit transport of positively charged ions; and    (D) a cathode electrode (140) including a second catalyst, having a first cathode surface, and an opposite second cathode surface, and configured to receive an oxidizing agent(s) along the second cathode surface, the second catalyst configured to react electrons with the oxidizing agent to create reduced species.
