    摘要： Disclosed is a separator for a fuel cell made of a metal plate coated with TiN, a polymer electrolyte membrane fuel cell comprising the separator and a method for manufacturing the separator. According to the invention, the separator can be made to be thin and it is possible to increase the power density, compared to the prior separator made of graphite. At the same time, a proper level of physical strength can be maintained, so that there is no problem of a breakdown by an external shock. In addition, the flow field can be easily formed and the cost is low. Additionally, the polymer electrolyte membrane fuel cell comprising the separator using a metal plate coated with TiN according to the invention has no problem of corrosion of metal separator due to the electrolyte, compared to the prior metal separator, so that the durability is excellent and the lifetime is long. In addition, when a mass-production system is established, the flow fields are provided by stamping a thin metal plate instead of forming the flow fields on the stainless steel plate, and then the two plates are brazed and coated with TiN, so that the weight of the stack is decreased.

    摘要： Disclosed is a three electrodes system cell for evaluation of performance of a molten carbonate fuel cell. A lower part of the reference electrode is fixed to a wet seal part of the single cell without penetrating a current collector plate and an electrode of the single cell. Preferably, the reference electrode comprises cured matrix slurry and powders of electrolyte stacked on the matrix slurry in the lower part thereof. Preferably, a diameter of an electrolyte-interchanging hole formed in a bottom of the lower part of the reference electrode is 1ψ. Preferably, an outer diameter of an alumina tube in the reference electrode is 6ψ. According to a three electrodes system cell for evaluation of performance of a molten carbonate fuel cell of the invention, it is possible to separately evaluate the performance of each electrode which cannot be evaluated by the prior method of evaluating the performance of the single cell. Particularly, contrary to the prior art, it is possible to prevent a crack of the matrix due to a physical shock and a heat shock resulting from the outflow and inflow of the supply gas, to reduce the gas leakage resulting from a decrease of adhesive strength between the matrix and the alumina tube and a heat shock due to the gas leakage, to improve the problem of electrolyte depletion and to reduce the physical defects resulting from a size of the reference electrode. Accordingly, it is possible to clearly measure the variation of the performance of each electrode while reducing the physical errors to the highest degree, to provide an exact criterion regarding the factor influencing on the variation of performance of the single cell when evaluating the performance of the single cell having 100 cm2 of large area, and to directly evaluate the performance of the molten carbonate fuel cell.
