Fuel cell stack, fuel cell and shell

Abstract

A fuel cell stack, includes a plurality of fuel cells. Each fuel cell includes a shell, an anode and a cathode mounted in the shell. A liquid storage chamber used for storing electrolyte and a communicating part used for communicating the liquid storage chamber are provided in the shell of each fuel cell. The liquid storage chambers of every two adjacent fuel cells communicate by the communicating part. The liquid storage chambers of every two adjacent fuel cells communicate through the communicating part, so that the electrolyte of each fuel cell can cross flow each other to make the electrolyte of each unit highly consistent. Therefore, the performance parameters of each fuel cell in the same fuel cell stack are basically the same, rendering the working performance of fuel cell stack improved. The present invention also relates to a fuel cell and a shell.
