Methanol reforming gas generator

Abstract

The invention relates to a high-temperature fuel cell, in particular to a methanol reformed gas generator for testing an electric pile of the high-temperature fuel cell. Comprising a hollow closed container, a partition plate is arranged in the container and divides the interior of the container into a left cavity and a right cavity which are not communicated with each other, the left cavity serves as a methanol gasification cavity, the right cavity serves as a methanol reforming cavity, and electric heating elements are arranged in the methanol gasification cavity and the methanol reforming cavity respectively. An electric heating element arranged on the methanol gasification cavity is used for heating the methanol gasification cavity, and an electric heating element arranged on the methanol reforming cavity is used for heating the methanol reforming cavity; a methanol inlet and an oxidant inlet are formed in the wall surface of the methanol gasification cavity, and a methanol reformed gas outlet is formed in the wall surface, far away from the methanol gasification cavity, of the methanol reforming cavity; a through hole is formed in the partition plate between the methanol gasification cavity and the methanol reforming cavity, and a mixed material of methanol and an oxidizing agent in the methanol gasification cavity enters the methanol reforming cavity through the through hole; and the methanol reforming cavity is filled with a methanol reforming catalyst.

Description

technical field [0001] The invention relates to a high-temperature fuel cell, in particular to a methanol reforming gas generator used for high-temperature fuel cell stack testing. Background technique [0002] Due to climate change and the fossil energy crisis, research and development of clean energy will be crucial in the coming decades. As one of the important clean energy sources, fuel cell has received more and more attention. Among them, high-temperature proton exchange membrane fuel cell is an electrochemical reaction device that directly converts the chemical energy of fuel into electrical energy, and has the ability to tolerate CO. Strong, fast electrode reaction rate and simple hydrothermal management advantages. [0003] However, in the research and testing process of high-temperature fuel cells, it is usually necessary to use an anode fuel containing CO or other inert gases for testing. The existing technology includes that the reformer is directly assembled o...

Problems solved by technology

The existing technology includes that the reformer is directly assembled on the test bench to prepare hydrogen-rich mixed gas. The main problem of this technical solution is that the temperature of the gas directly entering the battery reaction is too high, which makes the battery unable to operate stably for a long time. The test data Unreliable; Another solutio
