Problems solved by technology

In a conventional fuel cell system including such an injector, the pressure of the fuel gas on the downstream side (or upstream side) of the injector in the fuel supply flow path is detected, and feedback to the injector is performed based on the detected pressure. The control is as disclosed in Patent Document 1: Japanese Patent Laid-Open No. 2007-165237, but there are some defects and risks in this control method, for example, when the non-injection time (valve closing time) of the injector is extremely short, the The pressure detection error of the fuel gas near the upstream side or downstream side of the injector due to the influence of the air pressure vibration at the time of the valve becomes large, and the accuracy of the feedback control decreases.

Abstract

The invention discloses an intelligent fuel cell. The intelligent fuel cell comprises N fuel cell panels which are mutually separated through (N-1) insulating layers and contain printed circuit boardsintegrated with switches; each fuel cell panel can be independently switched through arranging at least one switch on each fuel cell panel. The intelligent fuel cell further comprises a controller for controlling the switching of the switches and a reactant supply pipeline and a cooling pipeline on the fuel cell, so that power output of the fuel cell is accurately controlled.

Description

technical field [0001] The invention relates to the technical field of electric energy storage, in particular to an intelligent fuel cell capable of precisely controlling output power. Background technique [0002] A power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy through an electrochemical reaction. Fuel cells can theoretically operate at close to 100% thermal efficiency, which is highly economical. Due to the limitation of various technical factors and considering the energy consumption of the whole device system, the total conversion efficiency of various fuel cells currently in operation is mostly in the range of 45% to 60%, and it can reach more than 80% if the utilization of exhaust heat is considered. In addition, fuel cell units have no or few moving parts, are reliable, require less maintenance, and are quieter than conventional generator sets. In addition, the electrochemical reaction is clean and comp...
