Problems solved by technology

[0004] From the above research questions, it can be seen that the fuel cell is facing two problems: one is how to avoid water blocking the flow channel of the first plate; the other is how to make the temperature of the first plate cool evenly; the third is how to sufficiently cool the overall temperature of the fuel cell

Abstract

The invention discloses a single fuel cell, a fuel cell stack and a working mode. The invention belongs to the technical field of new energy automobile fuel cells. The single fuel cell is characterized by comprising a second plate, a membrane electrode group and a first plate, the membrane electrode group is arranged between the second plate and the first plate; the upper side of the first plate is provided with a semi-water-drop-shaped protrusion protruding upwards and a semi-water-drop-shaped recess recessed downwards. The lower side of the first plate is provided with a semi-water-drop-shaped protrusion protruding downwards and a semi-water-drop-shaped recess recessed upwards. By adopting the single fuel cell, the fuel cell stack and the working mode, the stability of the fuel cell canbe effectively improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells for new energy vehicles, in particular to a single fuel cell, a fuel cell stack, and a working method. Background technique [0002] A typical structure of a single fuel cell includes: a first plate located on both sides, a second plate, and a membrane electrode group sandwiched between the first plate and the second plate. A fuel cell stack can be formed by stacking the above-mentioned single fuel cells. [0003] There are many studies on single fuel cells, for example: CN 110993984 A (Honda Technical Research Industry Co., Ltd.), CN110785881 A (Robert Bosch Co., Ltd.), CN106104878A (Volkswagen Automobile Co., Ltd.), CN105529487A (Toyota Motor Co., Ltd.), etc. . [0004] From the above research questions, it can be seen that the fuel cell is facing two problems: one is how to avoid moisture blocking the flow channel of the first plate; the other is how to make the temperature of the first pl...
