Fuel cell stack

A fuel cell stack comprising a plurality of membrane electrode assemblies and a plurality of separator members, the membrane electrode assemblies each including an electrolyte membrane, and electrodes provided on both sides of the electrolyte membrane, the membrane electrode assemblies and the separator members being stacked together alternately,

• wherein each of the separator members includes:
• a separator body stacked on the membrane electrode assembly;
• and
• a cell voltage terminal protruding outward from an outer peripheral portion of the separator body,
• the cell voltage terminal each comprises:
• a plate shaped terminal;
• a first protrusion protruding from the terminal toward one side in a stacking direction in which the membrane electrode assembly and the separator member are stacked together;
• and
• a second protrusion protruding from the terminal toward another side of in the stacking direction,
• and wherein at least some of the cell voltage terminals are arranged in a line in the stacking direction;
• and
• in the cell voltage terminals facing each other in the stacking direction, the first protrusion of one of the cell voltage terminals and the second protrusion of another of the cell voltage terminals face each other, and contact each other through an electrically insulating member.
