Problems solved by technology

But the invention patent application does not address the linear increase in the amount of signal transmission caused by multiple fuel cell units
In addition, since all signal processing data of the fuel cell system needs to be transmitted to the command controller through the CAN bus for processing, this technical solution cannot well solve the operation risk of the entire fuel cell system
In addition, since all signal processing data of the fuel cell system needs to be processed by a single controller, it will be difficult to ensure real-time control of all fuel cell units in actual operation
In addition, due to the data transmission through the CAN bus, when a fuel cell unit of the fuel cell system is damaged, it is difficult to locate and replace the damaged fuel cell unit
Finally, the technical solution provided by the invention patent application is aimed at water-cooled fuel cells, which is not applicable to air-cooled fuel cell systems

Abstract

The invention provides a fuel cell distributed control system and a control method. The system comprises a group of operation, detection and control units and a monitor, wherein the monitor is electrically connected with each operation detection and control unit; and each operation detection and control unit comprises a detection device used for detecting the operation state of a fuel cell, a regulation and control device and a controller electrically connected with the detection device and the regulation and control device, and the detection device is capable of detecting at least one operation state parameter of the fuel cell, converts the detected operation state parameter information into one operation state signal and sends the operation state signal to the controller of the operation detection and control unit.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a fuel cell distributed control system. The invention also relates to a fuel cell distributed control method. Background technique [0002] A fuel cell is an electrochemical device that directly converts the chemical energy of reactants into electrical energy. Such as figure 1 The shown proton exchange membrane fuel cell (PEMFC) consists of an electrolyte and a porous water-permeable cathode and anode connected to both sides of the electrolyte. The cathode and anode of the battery are mostly composed of a collector plate, a reaction gas flow channel, a gas diffusion layer (GDL), a microporous layer, and a catalytic layer. Among these components, the collector plate is a component that collects electrons and outputs electrical energy to the outside. , its material is generally composed of metals with high conductivity and mechanical stability; the reactant gas flow channel provides a flow channel...
