    摘要： An assembly for storing electrolyte in a carbonate fuel cell is provided. The combination of a soft, compliant and resilient cathode current collector and an inactive anode part including a foam anode in each assembly mitigates electrical contact loss during operation of the fuel cell stack. In addition, an electrode reservoir in the positive end assembly and an electrode sink in the negative end assembly are provided, by which ribbed and flat cathode members inhibit electrolyte migration in the fuel cell stack.

These components reduce the number of components necessarily handled in fuel cell assembly. The composite active electrolyte-matrix tape provides a major portion or all of the active electrolyte required by the entire cell for operation. The electrolyte matrix/cathode tapes laminate provides a supported electrolyte matrix structure resistant to cracking and fracture. Active electrolyte may also be added to either the electrolyte matrix, to the cathode, or to both tapes in the electrolyte matrix/cathode laminate to provide a major portion or all of the active electrolyte for cell operation.

    摘要： A molten carbonate fuel cell using molten carbonate as an electrolyte, carbonate ions as electric conductor, and feeding a hydrogen-enriched gas to the anode and a mixture of air and carbon dioxide gas to the cathode has its output fall by degrees with operation. It is surmised that one of the causes of this problem is ascribable to the fact that the molten carbonate electrolyte moves during operation to destroy equilibrium in the boundary between the electrolyte and electrodes. After studies for measures against the problem, the inventor found that the output of a fuel cell which has fallen can be improved by shutting off part or all of the raaction gases or reducing their feed for a while, and then restoring. The purpose of the present invention is to offer a high-performance stable-output molten carbonate fuel cell and its operation control method, incorporating the above findings in its operation control system.
