A preparation method of electrodes for the molten carbonate fuel cell

In order to explore an environmentally friendly approach to produce sintered electrodes that could be prepared continuously and could meet the requirements of MCFC, pasting slurry technique was adopted at different sintering temperature with nickel or nickel-plated punched steel sheet being the supporting material in the electrodes, aqueous solution of polyvinyl alcohol (PVA) and Carboxymethyl cellulose sodium (CMC) as the agglomerant, and T255 nickel carbonyl as the active substrate. And then, some testing methods such as kerosene immerging and scanning electron microscope (SEM) were used to test the rate of hole and the pattern of the electrodes. In addition, Thermogravimetric method was employed to test the heat and mass change of nickel slurry and electrochemistry performance of the single cell in assembled molten carbonate fuel cell (MCFC). The testing results show that the punched steel sheet electrode has better strength and electrochemistry performance than that of foam nickel; therefore, pasting slurry technique could prepare excellent electrodes required by MCFC in definite sintering conditions.
