Abstract

The present invention relates to the technical field of fuel cells, in particular to a method and device for improving the heat dissipation capacity of a fuel cell, and a fuel cell cooling system. The method for improving the heat dissipation capacity of a fuel cell includes: obtaining the current refractive index of the cooling liquid in the cooling pipe; The current freezing point value is obtained by the current refractive index; the display information of the instrument is controlled according to the current freezing point value; the opening of the radiator is controlled to increase or decrease according to the current freezing point value until the current freezing point value falls within the preset freezing point threshold. In the method for improving the heat dissipation capacity of the fuel cell of the present invention, the information is displayed according to the current freezing point value, and the opening of the radiator is controlled at the same time. cost, while controlling the opening of the radiator can improve the heat dissipation capacity of the fuel cell.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a method, a device and a fuel cell cooling system for improving the heat dissipation capacity of a fuel cell. Background technique [0002] At present, fuel cell buses are developing rapidly, and hydrogen fuel cell buses are blooming everywhere in various regions. [0003] The bipolar plate in the fuel cell engine requires a low corrosion rate to prolong the service life of the stack. Therefore, the cooling system of the hydrogen fuel cell has extremely high requirements on the cooling medium, and a special low-conductivity coolant needs to be used. Conductivity>2000μS / cm cannot meet the normal operation of fuel cell engine. Compared with traditional power, the suitable operating temperature of hydrogen fuel cells is 70-80°C. During operation, due to ohmic resistance, the condensation and heat release of water vapor generated, and the enthalpy change of electrochemical rea...
