The present invention relates to a molten carbonate fuel cell having a molten carbonate fuel cell.

崩壊してしまう現象が発生する。However, when an electrode made of nickel oxide is used as the cathode, the internal resistance of the battery increases considerably due to the high electrical resistance of nickel oxide, which causes the problem that sufficient single-cell performance cannot be obtained. Furthermore, when a porous nickel body is placed on the cathode side, the cathode side is in an oxidized state, resulting in a porous nickel oxide body. For this reason, a porous nickel sintered body is used as a cathode at the stage of assembling a fuel cell. However, before the porous sintered nickel is oxidized and becomes a porous body of nickel oxide, the electrode becomes powdered.
A phenomenon of collapse occurs.

材料で電極で構成した後還元処理することが望ましい。An IL electrode made of lithium-nickel oxide is particularly effective when used as a cathode in a molten salt type screw cell, but is it possible to use a lithium-nickel oxide before producing an electrode? It is desirable to perform a reduction treatment in advance on a material containing 1I, or to perform a reduction treatment after forming an electrode with a material containing a lithium-nickel compound.

An electrolyte sheet metal cathode and an anode with a diameter of 2 mm and a thickness of 2, is equipped with a fuel chamber and an oxidizer chamber, and also serves as a five-fold sleeping terminal. A single cell was formed in which the constituent parts were pushed out from both sides. A gas consisting of 50% hydrogen and 50% nitrogen is fed into the fuel chamber of such a single cell molten salt fuel cell as a fuel, and a gas consisting of 70% air and 30% carbon dioxide as an oxidizing agent is fed into the oxidizer chamber. The test results are shown in Table 1, in which the battery performance was evaluated at 650 C while the gases were supplied at a flow rate h1 of o and st/in, respectively.
