The invention provides a direct alcohol type fuel cell system, comprising a fuel tank, a cathode oxidizing agent feed subsystem, an anode fuel cycle subsystem and a galvanic pile, wherein the fuel tank is a close fuel tank, a high-concentration fuel is arranged in the fuel tank, and the fuel tank is communicated with the cathode oxidizing agent feed subsystem by a pipeline. The cathode oxidizing agent feed subsystem comprises a gas pump, the pipeline, and the like. When the air pump is in working, a cathode gas circuit has higher pressure. If the fuel tank is communicated with the cathode gascircuit, the cathode gas circuit can inflate the fuel tank to cause the gas in the tank to have higher pressure. The relatively high pressure and the pressure in an anode fuel mixing subsystem form pressure difference, the high-concentration fuel in the tank is controlled to be supplied to the anode fuel mixing subsystem by a valve under the action of the pressure difference, and the high-concentration ...

Принадлежит:

A water-pervious bipolar plate in a proton exchange membrane fuel cell has the functions of water permeating and air blocking, fuel cell generated water can be drained, and meanwhile it is guaranteed that oxidizing agent cavity gas does not run into a water cavity. In the running process of the fuel cell, when operation conditions are controlled improperly or the bipolar plate is damaged or sealing fails, air leakage is likely to happen to the water-previous bipolar plate, and the original air blocking function is lost. The invention relates to a method for detecting the water-pervious bipolar plate with the air blocking function lost in a multisection water-pervious plate fuel cell stack, the bipolar plate with the air blocking function lost is found fast to be treated under the conditions of not completely dismounting the stack, the high utilization rate of the oxidizing agent gas is guaranteed, meanwhile, complete dismounting of the stack and the influence on other assemblies in the ...
