NOVELTY - The module (100) has multiple stacked fuel cells (10), where each cell includes a membrane electrode assembly (1). Gas-permeable layers (2, 3, 5, 6) are placed on anode and cathode sides, where the gas-permeable layers sandwich the membrane electrode assembly. A separator (7) is placed on one of the anode and cathode sides. A gasket (8) is integrally molded with peripheral edges of the membrane electrode assembly and the gas-permeable layers of each of the stacked fuel cells. The separator has a protruding portion that protrudes laterally to an outer peripheral surface of the gasket.    USE - Fuel cell module for a fuel cell stack (claimed) utilized in an electric vehicle.    ADVANTAGE - The modules constitutes a fuel cell stack in which an electrolyte membrane of each fuel cell that forms the fuel cell stack can be effectively prevented from contamination i.e. adhesion with foreign materials, and with which effective maintenance can be carried out by removing only a fuel cell with degraded performance out of the fuel cell stack for replacement. The module can be easily removed during degraded performance so as to easily reproduce a fuel cell stack. The electrolyte membranes of the fuel cells that constitute the fuel cell modules or the fuel cell stack can be effectively protected against contamination with foreign materials in the production process of the fuel cell modules or stack, so that the maintenance efficiency can be significantly improved by removing a single fuel cell with degraded performance and removing after releasing stacking. The module provides a fuel cell stack with better electrical insulation properties from outside when a configuration in which separators are covered with a gasket is used.
