SOLID OXIDE FUEL CELLS

Accelerating oxygen surface exchange

Enhancing the oxygen exchange rate at the surface of oxides through rational design has long been a key goal of researchers pursuing sustainable energy solutions. Now, a simple infiltration method reveals that reaction rates on porous mixed-conducting oxides scale with the acidity of the infiltrate and can be tuned by orders of magnitude.
