Embodiment Construction

[0068] figure 1 It is a schematic diagram of a fuel cell failure prevention device according to the first embodiment of the present invention.

[0069] Please refer to figure 1 , the fuel cell 100 in the first embodiment includes a single cell 102, a pair of current collectors (current collectors) 104a and 104b positioned on both sides of the single cell 102, and a pair of end plates positioned beside the current collectors 104a and 104b, respectively. (end plate) 106a and 106b. The above single cell 102 may include a membrane electrode assembly (membrane electrode assembly, MEA) 108, an anode flow field plate (flow field plate) 110, a cathode flow field plate 112, an anode gas diffusion layer (gas diffusion layer, GDL) 114 and a cathode gas diffusion layer. layer 116, but the invention is not limited thereto. The anode flow field plate 110 includes anode flow channels 110a for transporting fuel (hydrogen), and the cathode flow field plate 112 includes cathode flow channels...

Abstract

A fuel cell failure prediction apparatus is provided. The prediction apparatus includes upstream and downstream voltage monitoring units, a data processing unit and a system control unit. The upstream and downstream voltages of each single cell may be synchronously monitored by the upstream and downstream voltage monitoring units. According to the monitored upstream and downstream voltages of each single cell, the data processing unit is used to obtain a differential voltage of the upstream and downstream voltages of each single cell. In accordance with the differential voltage, the system control unit performs a correcting control of failure prediction on the fuel cell.

Description

technical field [0001] The present invention relates to a fuel cell monitoring system, and more particularly to a method and preventive measures for performance degradation or failure caused by improper water management and stoichiometric management of a fuel cell system. Background technique [0002] With the advancement of industry, the consumption of traditional energy such as coal, oil and natural gas continues to rise. Due to the limited stock of natural energy, it is necessary to develop new alternative energy to replace traditional energy, and fuel cells are an important and unique energy. A choice of practical value. [0003] In simple terms, a fuel cell is basically a power generating device that converts chemical energy into electrical energy using the reverse reaction of electrolysis of water. Taking a proton exchange membrane fuel cell as an example, it is mainly composed of a membrane electrode assembly (MEA for short) and two electrode plates. [0004] Membra...
