1-34. (canceled)
A deionization fuel cell (DFC) comprising:
- a cathode;
- an anode;
- a catholyte flow channel;
- an anolyte flow channel, and at least:
- a cation exchange membrane (CEM);
- an anion exchange membrane (AEM), and a feedwater flow channel, wherein:
- the catholyte flow channel is disposed adjacent to the cathode, the anolyte flow channel is disposed adjacent to the anode, and the feedwater flow channel is formed between the CEM and the AEM and is configured for the deionization of feedwater;
- wherein the feedwater contains at least 10 mM of chloride ions (Cl−);
- wherein the cathode comprises a catalyst comprising a non-platinum group metal and a nitrogen doped carbon matrix;
- wherein the catalyst is configured to catalyze an oxygen reduction reaction (ORR) taking place at the cathode;
- and
- wherein the DFC is a non-biological DFC.
