1. A membrane electrode assembly comprising:
a cathode layer comprising a reduction catalyst;
an anode layer comprising an oxidation catalyst;
a membrane layer comprising a first ion-conducting polymer, the membrane layer arranged between the cathode layer and the anode layer and conductively connecting the cathode layer and the anode layer; and
a cathode buffer layer comprising a second ion-conducting polymer, the cathode buffer layer arranged between the cathode layer and the membrane layer and conductively connecting the cathode layer and the membrane layer, wherein the second ion-conducting polymer comprises an anion-and-cation conducting polymer.
