摘要：
A fuel cell is disclosed in which the cathode is a gaseous diffusion fuel cell electrode operating with an acid electrolyte and nitrogen dioxide (NO.sub.2) alone or with oxygen. The cathode half cell reaction produces nitric oxide (NO) and water and the NO.sub.2 is externally regenerated by reaction of NO with oxygen to produce the nitrogen dioxide for reuse in the cell. When both NO.sub.2 and oxygen are used, oxidation of the NO formed back to the NO.sub.2 occurs within the cathode itself so it is possible to get more than 100% utilization of the NO.sub.2 in the fuel cell.
