Abstract

The invention discloses a method for enhancing the operation stability of a fuel cell, which belongs to the technical field of fuel cells. The fuel cell can be operated alternately under different high and low currents. Compared with the traditional constant current operation mode, the loss of doping acid can be reduced under the premise that the power output capacity remains unchanged, which can effectively slow down the degradation of battery performance and significantly prolong the life of the fuel cell. operating life.

Description

technical field

[0001] The invention relates to the technical field of fuel cells, in particular to a method for enhancing the operation stability of fuel cells. Background technique

[0002] A fuel cell is a power generation device that directly converts chemical energy in fuel into electrical energy. It is not limited by the Carnot cycle and has a high conversion rate. With its advantages of high energy density and low pollution, it will become an ideal power source in the future. . Among them, the polymer electrolyte membrane fuel cell (PEMFC) has low operating temperature, fast start-up, high specific power, simple structure, high reliability, and truly "zero emission". preferred power generation source. However, in practical application, it faces problems such as fuel reforming and purification, difficult water and heat management, complex structure and high cost.

[0003] Increasing the operating temperature is considered to be an ideal way to solve the main problem...
