Problems solved by technology

The current heating method is mainly to generate high-temperature gas through fuel combustion, and then use the high-temperature gas to heat the vaporization chamber and reforming chamber. The gas is used as the heat exchange medium. Since the heat carried by the gas is small, the temperature difference between the farther and nearer positions from the heat source is large. , it is easy to cause the reforming chamber to be heated unevenly, so that the hydrogen production efficiency of the reforming becomes low, and it takes a long time to restart after stopping midway, which is generally 20

Abstract

The invention discloses a vaporization chamber of a methanol fuel cell, and belongs to the technical field of methanol fuel cells. According to the technical scheme, the vaporization chamber of the methanol fuel cell comprises an upper cover plate, a lower cover plate and a pure aluminum sealing pad arranged between the upper cover plate and the lower cover plate; a U-shaped flow channel is arranged in the lower cover plate; a methanol water inlet and a gas outlet are arranged in two ends of the U-shaped flow channel respectively; a partition plate is arranged in the middle of the U-shaped flow channel; an inlet of the U-shaped flow channel is connected with a methanol water inlet pipe; and the upper cover plate and the lower cover plate are provided with heating holes for placing electric heating rods. According to the vaporization chamber of the methanol fuel cell, a methanol water solution can be quickly vaporized to shorten the startup time of the methanol fuel cell.

Description

technical field [0001] The invention relates to the technical field of methanol fuel cells, in particular to a vaporization chamber of a methanol fuel cell. Background technique [0002] In the reforming hydrogen production part of the current methanol fuel cell, methanol water needs to be heated and vaporized, and then heated and reformed to complete the hydrogen production process. The whole process is an endothermic process, and the optimal reaction temperature is about 250 degrees. The current heating method is mainly to generate high-temperature gas through fuel combustion, and then use the high-temperature gas to heat the vaporization chamber and reforming chamber. The gas is used as the heat exchange medium. Since the heat carried by the gas is small, the temperature difference between the farther and nearer positions from the heat source is large. , it is easy to cause the reforming chamber to be heated unevenly, so that the hydrogen production efficiency of the refo...
