Our previous paper [1] has described an unconventional chemically regenerative redox fuel cell, including a modest amount of performance data, and has pointed out a number of problem areas. This paper describes additional work and some attempts that have been made to improve the cell performance in several of the problem areas described in the first paper. Two different redox fuel cell systems employing the V2+/V3+ and Mo3+Mo4+ redox couples as the anolyte, and a new NO3−/NO catalyst system for… Expand
High-Performance Chemically Regenerative Redox Fuel Cells Using a NO3- /NO Regeneration Reaction.
TLDR
The electrochemical cell using the nitrate reduction to NO at the cathode on the carbon felt and oxidation of H2 as a fuel at the anode showed a maximal power density of 730 mW cm-2 at 80 °C and twofold higher power density than the target power density in the H2 /O2 proton exchange membrane fuel cells (PEMFCs).
