Abstract

The invention relates to an operation method of a fuel cell system, a control device and a storage medium. According to the operation method of the fuel cell system, the fuel cell system at least comprises a fuel cell and a DC / DC converter which are connected, the DC / DC converter is used for receiving and adjusting the output current of the fuel cell, and the method comprises the following steps: constructing a relation function between the operation efficiency of the fuel cell system and the output current of the fuel cell, the relation function comprises a plurality of to-be-identified parameters; acquiring numerical values of a plurality of parameters to be identified according to the data set of the fuel cell system at the plurality of moments so as to acquire a current relation function; and according to the current relation function, obtaining the maximum operation efficiency of the current fuel cell system, and controlling the fuel cell system to operate at the maximum operation efficiency. According to the operation method of the fuel cell system, the fuel cell system can operate at the maximum efficiency so as to reasonably utilize energy.

Description

technical field [0001] The present application relates to the technical field of fuel cells and automatic control, in particular to an operating method, a control device and a storage medium of a fuel cell system. Background technique [0002] Energy has always been a prerequisite for the development of human society and economy. In recent years, with the continuous development of society, the depletion of oil resources and the increasingly severe climate and environment, the power system industry is reorganizing renewable energy power generation as an alternative solution, proton exchange membrane fuel Battery (Proton Exchange Membrane Fuel Cell, PEMFC) has received extensive attention and application in recent years because of its advantages of high efficiency and low emission. [0003] However, the efficiency characteristics of a fuel cell system are easily affected by many other factors, such as: operating temperature, gas flow rate, ambient humidity, etc. If the operat...
