Definitions
- the “composite separator plate” in the above-mentioned polymer electrolyte fuel cell of the present invention is a composite separator plate that also has a combined force of an anode-side separator plate and a force-sword-side separator plate, An anode-side separator plate and a force-side separator plate are integrally formed to form a separator plate! , U.
- FIG. 3 is a schematic cross-sectional view (cross-section in a direction perpendicular to the main surface 36) of the force-sword-side separator plate 30 shown in FIG.
- the anode-side separator plate 40 has a main surface (a portion corresponding to a region surrounded by a broken line) 46 in contact with the anode 23 and a main surface 46 surrounding the main surface 46. And a peripheral portion 47 integrally formed.
- the rim 47 has an oxidant gas maho A vent hole 42, a fuel gas manifold hole 43, and a cooling water manifold hole 44 are provided.
- the main surface 46 has a gas flow path 48 for supplying a fuel gas to the anode 23, and the gas flow path 48 is configured to communicate with the fuel gas manifold hole 43! RU
- the main surface 46 also protrudes outward (ie, the anode 23 side) in a convex shape, similarly to the main surface 36 of the force-sword-side separator plate 30 shown in FIG.
- a step is provided at the connection portion between the main surface 46 and the peripheral edge 47 of the plate 40, but the rear surface has a cooling water channel 45 and is configured to be a single flat surface with no step. ing.
- the average thickness of the main surfaces 36 and 46 is thicker than the average thickness of the peripheral portions 37 and 47, and the thickness of the thickest portion of the main surfaces 36 and 46 is different from that of the peripheral portions 37 and 47.
- the difference At (see FIG. 3) from the average thickness of the portion 47 is preferably 5-30 m. If it is less than 5 m, the contact resistance between the main surfaces 36 and 46 and the gas diffusion layer increases, and if it is more than 30 m, the gas diffusion layer becomes too crushed and the pressure loss increases. is there. Above all, from the viewpoint of more surely obtaining the effect of the present invention, the difference ⁇ t is preferably 5 to 10 ⁇ m!
- one of the pair of oxidant gas manifold holes 32 is an inlet, and the other is an outlet. Also, a pair of oxidizing gas manifold holes 42, a pair of fuel gas manifold holes 33, a pair of fuel gas manifold holes 43, a pair of cooling water manifold holes 34, and a pair of Similarly, in the case of the cooling water manifold hole 44, one is an inlet and the other is an outlet.
- no cooling section is provided inside the composite separator plate 50, but it is preferable to provide a cooling water flow path inside the composite separator plate 50 for every two or three MEAs.
- a cooling water flow path inside the composite separator plate 50 for every two or three MEAs.
