At cell operating temperatures of 650°C (1200°F) noble metal catalysts are not required.
The anode is a highly porous sintered nickel powder, alloyed with chromium to prevent agglomeration and creep at operating temperatures.
The cathode is a porous nickel oxide material doped with lithium.
Significant technology has been developed to provide electrode structures which position the electrolyte with respect to the electrodes and maintain that position while allowing for some electrolyte boil-off during operation.
The electrolyte boil-off has an insignificant impact on cell stack life.
