(EN) The present invention improves sealing of a combustion chamber or an air chamber by a sealing member. This fuel cell stack is provided with multiple power generation units, and is fastened with multiple fastening members. Each of the power generation units includes a single cell and a sealing member that is nipped between two other members to seal either a combustion chamber or an air chamber. Thesurface roughness Ra of a surface that is of the sealing member included in at least one of the power generation units and that opposes one of the two other members is not greater than 3.0 mum.
(ZH) 提高密封构件对于燃料室或者空气室的密封性。燃料电池堆包括多个发电单位并利用多个连结构件相连结。各发电单位包括单元电池和通过被其他的两个构件夹持而将燃料室和空气室中的一者密封的密封构件。至少1个发电单位所包含的密封构件的与其他的两个构件中的任一者相对的表面的表面粗糙度Ra为3.0μm以下。
