Patent abstract
Solid oxide fuel cells selectively transport oxygen ions through an electrolyte membrane. The maximum oxygen ion transport rate limits the power density of the fuel cell. By ion irradiating the electrolyte membrane and/or the cathode, the oxygen adsorption, dissociation, and incorporation rates can be improved, leading to higher ion transport rates and better fuel cell performance.
