ABSTRACT:
The present invention provides a molten carbonate type fuel cell comprising two electrodes as anode and cathode, an electrolyte plate and separators in a single unit and a battery of the unit cells stacked. The electrodes comprise a porous plate of an electron-conducting material such as nickel containing particles of ceramics such as magnesium oxide uniformly dispersed therein in an amount of 2 to 29 atomic %, except for the superficial thin portion free of the ceramic particles on the one-side surface of the plate. The electrodes are prepared by mixing a powder of the electro-conducting material with an organic binder under stirring to obtain a slurry or paste, deaerating the slurry or paste to remove entrained air bubbles therefrom, shaping the slurry or paste plate with or without a metal wire net, drying the electrode plate at room temperature and finally firing the plate in a reducing atmosphere.
