Embodiment Construction

[0027] figure 1 It is a schematic structural view of main parts of the solid polymer battery assembly 10 according to the first embodiment of the present invention.

[0028] The battery assembly 10 is configured by arranging a plurality of unit cells, for example, a first unit cell 12 and a second unit cell 14 with their electrode surfaces parallel to each other. Between the first and second unit cells 12 and 14, a connection channel member 16 is arranged. The first unit cell 12 constitutes a unit cell on the upstream side in the flow direction (arrow A direction) of the oxidizing gas (reactive gas). The second unit cell 14 constitutes a unit cell on the downstream side in the flow direction of the oxidizing gas.

[0029]The first and second unit cells 12 and 14 are provided with first and second junction bodies 18 and 20 . The first and second assemblies 18, 20 have, for example, solid polymer electrolyte membranes 22a, 22b impregnated with water in perfluorosulfonic acid ...

Abstract

A solid high polymer type cell assembly (10), comprising first and second unit cells (12, 14) arranged parallel with each other so that the electrode faces thereof are positioned parallel with each other, wherein an oxidizer gas flow passage (32) is allowed to linearly communicate from the first unit cell (12) to the second unit cell (14) through a first oxidizer gas passage (38) in the first unit cell (12), an oxidizer gas communication passage (40) in a connection flow passage member (16), and an oxidizer gas passage (42) in the second unit cell (14).

Description

technical field [0001] The present invention relates to a solid polymer battery assembly. The solid polymer battery assembly includes unit cells. A plurality of the unit cells are arranged side by side with their electrode surfaces parallel to each other to form an integrated battery assembly. The above-mentioned unit cell has an assembly in which a solid polymer electrolyte membrane is sandwiched between a positive electrode and a negative electrode. Background technique [0002] Generally, a solid polymer fuel cell (PEFC) uses an electrolyte membrane composed of a polymer ion exchange membrane (cation exchange membrane). This solid polymer fuel cell is equipped with a unit cell (unit power generation cell) in which an assembly (electrolyte-electrode assembly) is sandwiched by a separator (bipolar plate). Usually, the unit cells are stacked in a predetermined number of layers as fuel cell stacks. The above-mentioned assembly is formed by arranging a positive electrode and...
