Problems solved by technology

However, these methods are associated with corresponding technical defects
Constant current cold start takes a long time. If the constant voltage cold start is not well controlled in the early stage, it will easily fail. Constant power and maximum power cold start are difficult to achieve on the vehicle side, and external heating cold start will increase the complexity and energy consumption of the system.

Embodiment Construction

[0032] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the protection scope of the present invention. In the drawings, the same or similar reference numbers refer to the same or equivalent parts.

[0033] figure 1 A schematic structural block diagram of a control device 1 for controlling a cold start process of a fuel cell according to an exemplary embodiment of the present invention is shown. The control device 1 is configured to enable the fuel cell to start up at a lower ambient temperature, especially at a subzero temperature (eg, minus 50° C. or lower) by controlling the operating parameters of the fu...

Abstract

The invention relates to a method (100) for controlling a cold start process of a fuel cell, comprising at least the following steps: i) in a first phase, operating the fuel cell at an initial current density that is constant over time; and ii) operating the fuel cell at a current density that increases over time in a second phase immediately following the first phase. The invention also relates to an apparatus for controlling a cold start process of a fuel cell as well as a corresponding computer readable storage medium and a computer program product. According to the invention, the fuel cell cold start method which is short in start time, easy to control and free of additional system complexity and energy consumption is realized.

Description

technical field [0001] The present invention relates to a method for controlling a cold start process of a fuel cell and a device for controlling the cold start process of a fuel cell. Furthermore, the present invention also relates to corresponding computer-readable storage media and computer program products. Background technique [0002] Due to the presence of reaction product water and humidified water in a proton exchange membrane fuel cell (PEMFC), when it is shut down in an environment below 0 °C, the water in the cell will freeze, and the ice layer will hinder the electrochemical reaction process. , causing the battery to fail to restart again. Subzero outdoor temperature always occurs in cold winter, which is a severe test for the successful cold start of proton exchange membrane fuel cells installed in vehicles. [0003] In the prior art, in order to realize the cold start of the fuel cell, there are usually the following modes: constant current cold start, const...
