Embodiment Construction
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0044] As mentioned in the background technology, proton exchange membrane fuel cell vehicles are more efficient and can achieve zero emissions. Compared with pure electric vehicles, the time to replenish energy is shorter and the cruising range is longer. It is one of the directions of future vehicle development. However, at present, during the reaction process of the proton exchange membrane fuel cell, some impurities in the air (mainly nitrogen) will permeat...

The invention provides an impurity exhausting control method, system and device for a hydrogen path of a proton exchange membrane fuel cell. The control method comprises that a work mode of the protonexchange membrane fuel cell is determined; and according to the work mode of the proton exchange membrane fuel cell, a corresponding control mode is used to control impurity exhausting of the hydrogen path. Thus, the proton exchange membrane fuel cell can be controlled to exhaust impurities from the hydrogen path, the impurity content in the hydrogen path is reduced, and high efficiency and longservice life of the proton exchange membrane fuel cell can be ensured. In the impurity exhausting control process of the hydrogen path, the control model corresponding to the present work mode of theproton exchange membrane fuel cell can be used to exhaust the impurities from the hydrogen path, so that the control method is more flexible and efficient.
Description
technical field [0001] The invention relates to the field of impurity discharge in the hydrogen channel of a proton exchange membrane fuel cell, in particular to a method, system and device for controlling the impurity discharge in a hydrogen channel of a proton exchange membrane fuel cell. Background technique [0002] Proton exchange membrane fuel cell vehicles are more efficient and can achieve zero emissions. Compared with pure electric vehicles, the time to replenish energy is shorter and the cruising range is longer. It is one of the directions of future vehicle development. However, at present, during the reaction process of the proton exchange membrane fuel cell, some impurities in the air (mainly nitrogen) will permeate into the hydrogen path through the proton exchange membrane to affect the reaction rate of the fuel cell, thereby affecting the efficiency of the proton exchange membrane fuel cell and longevity. Contents of the invention [0003] In view of this,...
