Embodiment approach

[0095] Optionally, in another embodiment of the present application, an implementation of a power recovery device for a fuel cell engine further includes:

[0096] The first operating unit is configured to determine that the ratio of the actual voltage value at the current current to the set value is not within the preset range, or the ratio of the actual voltage value at the current current to the set value is within the range if the first judging unit 201 judges that Within the preset range but not for the first preset time, the fuel cell engine is controlled to continue to operate normally according to the original setting procedure.

[0097] For the specific working process of the units disclosed in the above embodiments of the present application, please refer to the content of the corresponding method embodiments, such as figure 1 shown, and will not be repeated here.

[0098] Optionally, in another embodiment of the present application, an implementation of a power rec...

Abstract

The invention provides a power recovery method of a fuel cell engine, a related device and a storage medium. The power recovery method of the fuel cell engine comprises the steps of in the operation process of the fuel cell engine, judging whether the ratio of a voltage actual value to a set value under the current current is within a preset range, and lasts for first preset time or not; and if it is judged that the ratio of the actual voltage value under the current current to the set value is within the preset range and lasts for the first preset time, starting a preset automatic recovery program, and recovering the power of the fuel cell engine by controlling the operation state of the fuel cell engine, thereby achieving the purpose of efficiently solving the problem that the power of the fuel cell engine is reduced.

Description

technical field [0001] The present application relates to the technical field of engines, and in particular to a power recovery method for a fuel cell engine, a related device and a storage medium. Background technique [0002] Due to the advantages of high energy conversion efficiency, zero pollution, stable operation, and no noise, fuel cells are the ultimate power solution for future vehicles. At present, they have become a research and development hotspot for related companies and units at home and abroad, and are in the early stages of industrialization. [0003] At present, during the operation of a car equipped with a fuel cell engine, there will be a reduction in power, which may be caused by flooding of the fuel cell stack or a reduction in the activity of the catalyst on the membrane electrode. However, in the prior art, maintenance personnel are usually required to go to the site to troubleshoot problems, or do not deal with them, and the efficiency is extremely l...
