Abstract

The invention relates to a fuel cell cooling circulation water tank heating device comprising a fuel cell system and also comprises a circulation water tank heating system which comprise a heating control management unit, an electrical heated tube, a high-voltage contactor and a temperature sensor, wherein the heating control management unit is connected with the high-voltage contactor, carries out data exchange with the control unit of the fuel cell system and is connected with the temperature sensor; the electrical heated tube is arranged in a circulation water tank; the electrical connecting line of the electrical heated tube is led out of the circulation water tank and is connected with the load line of a fuel cell through the high-voltage contactor; and the temperature sensor is arranged in the circulation water tank. The invention has the advantages that the preheating time of the fuel cell is shortened to make the fuel cell rapidly enter the best working state; the heating device is arranged in the water tank, thus, the water holding space is big and the local overheating is not easy to generate; the device has multiple protection and is safe and reliable; the electrical heated tube with different resistance can be selected according to different power generation output of the fuel cell, thus the device has wide the range of application. The device has simple function and great significance and is convenient to implement.

Description

technical field [0001] The invention relates to the field of fuel cell technology, in particular to the low-temperature operation technology of a fuel cell power generation system. Background technique [0002] The best working state of the proton exchange membrane fuel cell is the running state after the fuel cell reaches a certain temperature. Generally, it takes a long time to enter the best working state after power-on, after starting operation, and this process depends on Part of the heat generated by the operation of the fuel cell stack is used to increase the temperature of the fuel cell stack. The lower the ambient temperature is, the longer the heating process is required. In order to shorten the time for the fuel cell to enter the optimal working state, there is a method of heating the electric stack with a resistance wire in the prior art. Its disadvantages are: it is difficult to make, and the heating is not easy to control. Contents of the invention [0003]...
