Problems solved by technology

[0009] Therefore, the temperature at the central part in the direction in which the fuel cells are arranged becomes high, and the temperature at the end parts in the direction in which the fuel cells are arranged becomes low. Therefore, as a fuel cell group, the temperature in the direction in which the fuel cells are arranged Distribution becomes uneven (Yamagata), power generation efficiency may decrease

Abstract

Provided is a fuel battery cell stack capable of improving generation efficiency by uniformizing the temperature distribution I n the arrangement direction of the fuel battery cells in a fuel battery cell stack where a plurality of fuel battery cells are aligned. Each of the fuel battery cells (2) is formed by a fuel cell side electrode layer (5), a solid state electrolyte layer (6), and air side electrode layer (4) which are successively layered on a support substrate (8). The fuel battery cells (2) are electrically connected in series to one another in the fuel battery cell stack (1). The interval between fuel battery cells (2) arranged at the center portion in the arrangement direction of the fuel battery cells (2) is set greater than the interval between the fuel battery cells (2) arranged at the end portion side in the arrangement direction of the fuel battery cells (2). This can substantially uniformize the temperature distribution of the fuel battery cell stack (1).

Description

technical field [0001] The present invention relates to a fuel cell group in which a plurality of fuel cell cells are arranged, and a fuel cell in which a fuel cell group is accommodated. Background technique [0002] In recent years, as a next-generation energy source, a fuel cell in which a fuel cell group is housed in a container is proposed, and the fuel cell group has a large number of fuel cell cells that can obtain electric power using fuel gas and air (oxygen-containing gas). , and connect them electrically in series. [0003] Hydrogen is used as a fuel gas used for power generation in the fuel cell, the hydrogen is brought into contact with the fuel-side electrode layer of the fuel cell, and the oxygen-containing gas is brought into contact with the air-side electrode layer of the fuel cell to generate a predetermined electrode reaction, Power generation is thereby performed. [0004] Here, various fuel cell groups in which a plurality of fuel cells are arranged h...
