摘要： PURPOSE:To prevent the degradation of the activity of a reform catalyst, so as to enable stable operation of the fuel cell in the caption to be carried out reliably for a long period by providing an electrolyte removing material which removes an electrolyte or material generated from the electrolyte for fuel gas. CONSTITUTION:Between a fuel gas side electrode 2 and a reforming catalyst 7 is interposed an electrolyte removing material 8 which is capable of removing for fuel gas an electrolyte or material generated from the electrolyte by, for example, chemical reaction. Therefore, the electrolyte or the material generated from the electrolyte included in the fuel gas returning from the fuel gas side electrode 2 to a fuel gas path and the electrolyte removing material 8 are removed by chemical reaction. Thus the reforming catalyst 7 is prevented from being contaminated by the electrolyte or the material generated from the electrolyte, to enable the catalytic activity of the reforming catalyst to be maintained stably for a long period of time.

摘要： PURPOSE:To prevent consumption of an electrolyte while checking corrosion of the rail part by coating the rail part of a bipolar plate with an electrolyte- proof electrical insulator. CONSTITUTION:An electrolyte-proof electrical insulator 11 coating the rail part 8a of a bipolar plate 8 is so formed as to coat, for instance, the outer surface 8b, inner surface 8c and the wet seal opposite surface 8d. The insulator 11 is desirably to be, for instance, ceramics of Al2O3, MgO, Y2O3, ZrO2 and LiAlO2 from the viewpoint of corrosion resistance to molten carbonate while especially Al2O3 and LiAlO2 are excellent in stability. As a coating method, for instance, solve-shooting according to a method of plasma spraying or the like is practical. Thereby, the rail part 8a comes to contact with the electrolyte through the insulator 11 while being electrically insulated to check movement of electrons thus causing no local cell reaction and removing a leak current. Further, since the insulator 11 stable to the electrolyte is used, corrosion resistance of the rail part 8a also is improved.
摘要翻译：目的：为了防止电解液消耗，同时通过用耐电解质电绝缘体涂覆双极板的轨道部分来检查轨道部分的腐蚀。构成：涂覆双极板8的轨道部分8a的耐电解质电绝缘体11被形成为涂覆例如外表面8b，内表面8c和湿密封相对表面8d。从对熔融碳酸盐的耐腐蚀性的观点出发，绝缘体11优选为例如Al 2 O 3，MgO，Y 2 O 3，ZrO 2和LiAlO 2的陶瓷，特别是Al 2 O 3和LiAlO 2的稳定性优异。作为涂布方法，例如，根据等离子喷涂等的解决方法是实用的。由此，轨道部分8a通过绝缘体11与电解质接触，同时电绝缘以检查电子的运动，从而不引起局部电池反应并且消除泄漏电流。此外，由于使用对电解质稳定的绝缘体11，所以轨道部8a的耐腐蚀性也得到提高。

摘要： PURPOSE:To obtain an electrolyte layer having strong mechanical strength, low internal resistance, and the degree of freedom against deformation by staking and combining a matrix type electrolyte-holding agent and paste type electrolyte- holding agents. CONSTITUTION:A matrix type electrolyte-holding agent 16 and paste type electrolyte-holding agents 17 are stacked and combined. For example, LiAlO2 powder is mixed with an organic binder to form a green tape, which is calcined to sinter LiAlO2 grains, and the skeleton of the matrix type electrolyte-holding agent 16 is formed. On the other hand, a green tape made by molding LiAlO2 powder is used for the paste type electrolyte-holding agent 17. Then, the paste type electrolyte-holding agents 17 are stacked and combined on the matrix type electrolyte-holding agent 16 like a sandwich to form the skeleton of a hybrid type electrolyte layer 8, and gaps of the LiAlO2 skeleton are filled with fused carbonate to form the ion-conductive hybrid type electrolyte layer 8.

摘要： PROBLEM TO BE SOLVED: To improve the charging efficiency, and to stably house rectangular batteries by having recessed parts for abutting on a battery element while filling a clearance between the battery element and side surfaces of a package cover and having flat parts for abutting on a side surface of an adjacent package cover when adjacent rectangular batteries are turned over each other. SOLUTION: A rectangular battery is formed of a package cover 3 formed into a box shape opened in a lower surface thereof and having a trapezoidal cross section and a flat package bottom 4 for sealing the lower surface of the package cover 3. Opposite side surfaces of the package cover 3 respectively have recessed parts 3a for abutting on a battery element 1 while filling a clearance between the battery element 1 and flat parts 3b for abutting on other flat part of a side surface of an adjacent package cover 3 when adjacent rectangular batteries are turned over each other. With this structure, deformation of the side, surfaces of the package cover 3 can be prevented at the time of sealing in the condition that pressure is reduced. Breakdown of a lead 2 due to the vibration at the time of fixing the battery element 1 is prevented by the recessed parts 3a formed in the package side surfaces of the rectangular battery. The recessed parts 3a are formed so as to be adhered to the side surface of the battery element 1.

摘要： PROBLEM TO BE SOLVED: To restrict the corrosion of a metal member on the oxidant side being generated during temprature rise at the starting operation. SOLUTION: At least one of members which are exposed to an oxygen containing atmosphere during operation and whose surface is wetted by fused electrolyte is formed of stainless steel with a chrome content of less than 23wt%. Mixed carbonate, which contains 45-65mol% lithium carbonate and in which other sodium carbonate than lithium carbonate accounts for 50mol% or more, is used for electrolyte. The electrolyte is contained in a collecting plate 8 on the oxidant electrode side or in pores in an oxidant electrode 3 during staring operation. In a temperature rise process at starting operation, oxygen partial pressure in the atmosphere contacted by the oxidant electrode is kept to be 0.01atm or less or 0.08atm-0.12atm or carbon dioxide partial pressure is kept to be 0.05atom or less, for all period or at least 30 minutes from the melting point of the electrolyte to any battery temperature, higher than the melting point and 570 deg.C or less.
