摘要:
Anodes having NiCo.sub.2 O.sub.4 catalyst used in the electrohydrodimerization of acrylonitrile to adiponitrile result in anode voltage requirements of less than about 2000 millivolts at 100 milliamperes per square centimeter of anode area. Typically, oxygen evolving anodes comprised of lead or carbon steel are utilized in the hydrodimerization of acrylonitrile to adiponitrile resulting in high voltage requirements. Anodes containing NiCo.sub.2 O.sub.4 catalyst require substantially reduced voltages and perform well in the conventional electrochemical adiponitrile production environment.

A molten carbonate fuel cell ceria anode and a molten carbonate fuel cell including such anode are described. The ceria anode, in addition to having the requisite electrolyte compatibility, catalytic activity, and electron conductivity, has improved oxidation resistance and structural stability as well.
摘要:
A matrix for retaining the electrolyte in a fuel cell is applied to the surface of one or both of the electrodes by screen printing. In a preferred embodiment an aqueous solution of glycol is used as the inking vehicle to screen print a very thin, continuous and uniform matrix layer on the surface of an electrode.
