Control method for fuel cell safety operation

Abstract

This invention relates to a control method for the safety operation of fuel batteries, which timely monitors the operating fuel battery stack with a central processor, automatically cuts off the abnormal ones from the primary circuit of a stack in operation and cuts in the standby batteries into the primary circuit, which can test the abnormal batteries from the stack in operation and replace them automatically to guarantee the stack to work safely under the rating power.

Description

technical field [0001] The present invention relates to a fuel cell, in particular to a fuel cell that can disconnect an abnormal fuel cell in a fuel cell stack from the main circuit, and connect a backup battery to the main circuit, thereby ensuring the safe operation of the fuel cell that is normally working in the fuel cell stack control method. Background technique [0002] A fuel cell is a battery that converts chemical energy directly into electrical energy. It has the characteristics of high efficiency, less pollution and low noise. Like ordinary batteries, fuel cells have positive and negative electrodes and separator materials. In fuel cells, air and oxygen are generally used as oxidants, and hydrogen or methanol, ethanol, etc. are used as fuels. The positive and negative electrodes are separated by a diaphragm, which is a water-permeable and air-tight film, which can prevent the oxidant and fuel from mixing and exploding. There are also catalysts on both sides of...
