Document Type and Number:
Japanese Patent JP2023123116
Kind Code:
A
Abstract:
To provide a fuel cell stack in which side flow of cooling medium can be suppressed.SOLUTION: A fuel cell stack is formed by laminating a plurality of single cells 90 each comprising an MEA (Membrane Electrode Assembly), a first separator 30, and a second separator 40. The first separator 30 has first protruding portions 50 abutting on the second separator 40 of the other single cell 90 adjacent to the concerned single cell 90. A plurality of the first protruding portions 50 are provided outside an outside groove flow channel and arranged in a second direction Y. The second separator 40 has a plurality of second protruding portion 60 abutting on the first protruding portion 50. A second recessed portion 62 is provided at a center portion in the second direction Y, of a distal end portion 61 of each second protruding portion 60. A length L of the second recessed portion 62 is larger than a width W1 of the first protruding portion 50.
