Fuel cell

Abstract

The present invention provides a fuel cell comprising a pair of electrodes arranged on the inner and outer surfaces of a hollow electrolyte membrane, and at least two adjacent battery module assemblies connected in series, each assembly having a pair of electrodes respectively in contact with the paired electrodes. A plurality of current collectors having at least one open end. When connecting battery module assemblies in series, a problem arises that complicated gas flow channels must be provided on the inner surfaces of the battery modules. In order to solve the above-mentioned problems of the fuel cell, each of the above-mentioned battery module assemblies (100) is provided with: a partition wall (8A) (8B) for separating the space between the main body of the battery module array and the open ends, the open ends being aligned with each other , and a negative output unit (14) and a positive output unit (15), which are respectively connected with a negative current collector (12) and a positive current collector (13), and a negative current collector (12) ( 13) Arranged near the end side of the battery module and provided on the contact surface of the adjacent battery module components.

Description

technical field [0001] The present invention relates to a fuel cell including a battery module assembly in which two or more of the battery modules each having a hollow-shaped electrolyte membrane are integrally fixed. Background technique [0002] The fuel cell supplies fuel and oxidant to two electrodes electrically connected to each other to cause electrochemical oxidation of the fuel, so that chemical energy is directly converted into electrical energy. Since it is not limited by the Carnot cycle unlike thermal power generation, it exhibits high energy conversion efficiency. A solid polymer electrolyte fuel cell is a fuel cell using a solid polymer electrolyte membrane as an electrolyte, and has advantages such as being easy to downsize or operating at a low temperature, and therefore, it is attracting attention in application to power sources for portable or mobile products. people's interest. [0003] In a solid polymer electrolyte fuel cell, if hydrogen is used as f...

Problems solved by technology

Therefore, if a dead-end type battery module in which only one end of the battery module is open is used, there is a problem that two types of battery module assemblies (which have opposite positions of positive and negative electrodes) must be manufactured, or complicated battery modules must be provided. Gas channel to supply reactant gas to the inside of the battery module
