摘要： PROBLEM TO BE SOLVED: To make electric connection with neighboring cells easier by reducing an inner resistance of a solid oxide fuel cell SOFC. SOLUTION: The fuel cell includes an electrolyte, an anode formed on one side of the electrolyte, a cathode formed on the other side of the electrolyte, with the anode and the cathode formed of a composite material of the solid electrolyte and a good electronic conductor. A chemical composition of the anode or the cathode is inclined in a direction of reducing a solid electrolyte density as either separates from the solid electrolyte, and a void ratio of the anode or the cathode is inclined in a direction of increasing as it separates from the solid electrolyte. Thus, deletion of an auxiliary electrode carried out through gradient functionalization of a chemical composition of cermets composed of the solid electrode and a good conductor of metal forming the anode leads to low resistivity, and by forming an outer layer of the multilayer anode of a soft porous good conductor of metal, direct connection with interconnectors of the neighboring cells is made possible.

摘要： PROBLEM TO BE SOLVED: To satisfy both shortening of starting time and enhancing of power generation efficiency in a fuel cell power generation system having a fuel treatment device and a fuel cell. SOLUTION: In a fuel cell system comprising the fuel treatment device having a reforming catalyst and the fuel cell, in starting, the fuel treatment device is operated by an inner heat method in which a part of fuel to be reformed is oxidized to make a reformed heat source, and in a stationary operation, the fuel treatment device is operated by an outer heat method in which a reforming catalyst is heated by an outside heat source. Advantages of both of the inner heat type fuel treatment device having quick starting time and low efficiency and the outer heat type fuel treatment device having slow starting time and high efficiency can be exhibited. If an inner heat burner and an outer heat burner are used in starting, starting time can be more shortened than use of only the inner heat burner. When a combustion catalyst is used in the inner heat burner and a cluster burner is used in the outer heat burner, since metal is not heated to the unnecessary temperature, inexpensive metal can be used, and a system having quick starting time, high efficiency, and low cost can be provided.

摘要翻译：解决的问题：为了满足具有燃料处理装置和燃料电池的燃料电池发电系统的起动时间缩短和发电效率的提高。解决方案：在包括具有重整催化剂和燃料电池的燃料处理装置的燃料电池系统中，在起动时，燃料处理装置通过内部热法运行，其中将要重整的燃料的一部分氧化成制成重整热源，在固定运转中，燃料处理装置通过外加热方式加热重整催化剂的外加热方式运转。能够显示起动时间快，效率低的内热式燃料处理装置和启动时间慢，效率高的外加热型燃料处理装置的优点。如果在启动时使用内部加热燃烧器和外部加热燃烧器，则比仅使用内部燃烧器的启动时间更短。当在内部加热燃烧器中使用燃烧催化剂并且在外部热燃烧器中使用集束燃烧器时，由于金属不被加热到不需要的温度，因此可以使用便宜的金属，并且具有快速起动时间，高效率的系统，并且可以提供低成本。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a stacked fuel cell having high power generation efficiency and stable power generation performance by quickly draining water even when produced water by power generation or condensed water of water vapor flows in a reaction gas passage of a unit cell. SOLUTION: The gas passage in a unit cell is divided into a plurality. The length of the passage of reaction gas is shortened by just that much of the number of the divided passages, and when condensed water flows in the reaction gas passage or when the condensed water is produced in the reaction gas passage, the residence time of the condensed water in the reaction gas passage can be shortened. As a result, the flow rate distribution of the reaction gas supplied to each unit cell is made equal, power generation efficiency is enhanced, and power generation output is stabilized.
