NiO solubility in mixed alkali/alkaline earth carbonates

NiO cathode solubility in molten carbonate is a major technical obstacle to fuel cell commercialization. Addition of 1% SrO to the Li sub 2 CO sub 3 -K sub 2 CO sub 3 eutectic melt electrolyte reduces NiO solubility fifteenfold under the acidic conditions prevailing for such cells.
