Fuel cell and system, control method, control system and electrical apparatus

Abstract

Embodiments of the present invention provide a fuel cell and system, a control method, a control system, and an electric device, wherein the fuel cell is configured to be connected to a load comprising at least a rechargeable power source, and the fuel cell comprises a fuel cell stack module. The control system comprises a detection module adapted to detect the remaining power of the rechargeablepower supply in real time; DC/DC converter of fuel cell; The fuel cell controller module is adapted to control the DC/DC converter to output constant power to the terminal of the load according to thepreset power corresponding to the remaining power. By using this control system, the power supply of the equipment can be increased without destroying the internal structure of the original power supply system of the existing equipment. When combined with the multi-power platform, the idle standby state and/or the variation time of the off-load condition can be prolonged, the starting times and/or the frequent off-load operation state can be reduced, thereby prolonging the service life of the battery.

Description

technical field [0001] Embodiments of the present invention relate to the battery field, and more specifically, embodiments of the present invention relate to a fuel cell and system, a control method, a control system, and an electric device. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy. It converts the Gibbs free energy part of the chemical energy of the fuel into electrical energy through an electrochemical reaction. A stack module of a fuel cell usually includes components such as electrodes, electrolyte membranes, and current collectors. Fuel cell is a new type of battery with high conversion efficiency and low pollution. [0003] Fuel cells can be used in many ways. Taking the application of fuel cell energy enhancement (such as range extension) as an example, the existing pure electric vehicles (battery vehicles) can greatly increase the range after installing fuel cells (such...
