Reactor

Abstract

A reactor supplied with a reactant to cause reaction of the reactant includes a reaction device which has a hollow box type member having a top plate and a bottom plate opposed to each other and side plates connected to an edge of the top plate and an edge of the bottom plate. A partition member is housed in the box type member, the partition member coming into contact with at least internal faces of the side plates of the box type member and partitioning a space in the box type member into a plurality of reaction chambers to which the reactant is to be supplied. A penetrating region is provided in the partition member to connect the adjacent reaction chambers to each other, the penetrating region having the reactant passed therethrough. A flow channel through which the reactant flows is formed inside of the reactor by a partition member, the flow channel is wobbled, meanwhile the rigidity of the reaction device is improved.

Description

technical field [0001] The present invention relates to a reaction device which is supplied with reactants to cause the reactants to react. Background technique [0002] In recent years, the development of loading fuel cells, which are clean power sources with high energy conversion efficiency, into automobiles and portable devices has been progressing. A fuel cell is a device that electrochemically reacts fuel with oxygen in the atmosphere, thereby directly obtaining electrical energy from chemical energy. [0003] As a fuel used in a fuel cell, simple hydrogen is mentioned, but it is a gas at normal temperature and normal pressure, so there is a problem in terms of handling. Although attempts have been made to store hydrogen by hydrogen storage alloys, the amount of hydrogen stored per unit volume is small, especially as a fuel storage device for power supplies of small electronic devices such as portable electronic devices, and such storage is not sufficient of.

Problems solved by technology

However, in order to reduce the cross-sectional size of the flow path and increase the length of the flow path, it is necessary to form a meandering fine flow path inside the reactor. In order to increase the flow path length, it is necessary to design a complicated flow path structure, which complicates assembly.

[0008] In addition, in order to carry out the reaction in the reactor smoothly, the reactor is heated to a temperature suitable for the reaction while maintaining at a predetermined temperature. In order to reduce the loss of heat energy, the reactor is often designed so that its surroundings are in a vacuum state. Vacuum heat insulation structure, but in order to reduce the weight of the reactor, when the thickness of the metal substrate constituting the reactor is thinned, since the rigidity of the reactor is reduced, the reactor is often deformed due to the stress generated by the pressure difference, or the reactor is damaged. destroy
