Alcohol reforming fuel cell system

Abstract

The invention discloses an alcohol reforming fuel cell system, and aims to improve the heat exchange capacity of a reactor on the premise of not influencing the flow capacity of the reactor. Therefore, the alcohol reforming fuel cell system provided by the embodiment of the invention comprises an evaporation plate, a first heat transfer partition plate, a fuel cell, a second heat transfer partition plate and a reforming plate which are sequentially overlapped, an evaporation chamber is formed between the evaporation plate and the first heat transfer partition plate, and a reforming chamber is formed between the second heat transfer partition plate and the reforming plate; gas discharged from an outlet of the reforming chamber enters a hydrogen inlet of the fuel cell after gas-liquid separation, the evaporation chamber is composed of a snakelike straight micro-channel or a snakelike corrugated micro-channel, and the reforming chamber is composed of a snakelike straight micro-channel or a snakelike corrugated micro-channel.

Description

technical field [0001] The invention belongs to the technical field of energy and power, in particular to an alcohol reforming fuel cell system. Background technique [0002] With the depletion of fossil energy sources such as petroleum and coal, renewable energy sources have become increasingly prominent. Among them, the utilization and development of hydrogen energy is very urgent. Fuel cells are the best way to harness hydrogen energy. Hydrogen production by steam reforming of alcohols is the main hydrogen production technology for fuel cells. However, the existing real-time hydrogen production technology of alcohol reforming is currently limited by the poor performance of the reactor, and the recently emerging microreactor has attracted wide attention due to its microchannel structure. However, the heat exchange capacity and flow capacity of traditional microchannels are mutually restricted to a certain extent, which in turn limits the hydrogen production performance ...

Problems solved by technology

However, the existing real-time hydrogen production technology of alcohol reforming is currently limited by the poor performance of the reactor, and the recently emerging microreactor has attracted wide attention due to its microchannel structure.

However, the heat exchange capacity and flow capacity of traditional micro-channels limit each other to a certain extent, which in turn limits the hydrogen production performance of alcohol reforming in micro-reactors, which needs further design and optimization.
