Abstract

The invention relates to an insulating collector plate and a fuel cell. The insulating collector plate comprises a plate core module and an insulating plate module, the center of the insulating plate module is provided with a groove structure, the shape of the plate core module is matched with the shape of the groove structure, the plate core module is embedded in the groove structure, the insulating module is provided with an open slot, one end of the open slot is connected with the groove structure, the other end of the open slot is connected with the edge of the insulating plate module, a leading-out end is arranged on the plate core module, after the plate core module is embedded into the groove structure, the leading-out end is embedded into the open slot, and the end part of the leading-out end is suspended outside the insulating plate module. Compared with the prior art, the collector plate has the advantages that the sealing property and the insulating property of the collector plate can be improved, so that a reaction substance does not contact with the plate core module in the working process of the battery, and a complete insulating effect is achieved.

Description

technical field

[0001] The present invention relates to the technical field of fuel cells, in particular to an insulating current collector plate and a fuel cell. Background technique

[0002] The proton exchange membrane fuel cell is a kind of electrochemical process in which the anode hydrogen is decomposed into protons and electrons through a catalyst, the protons reach the cathode through the proton exchange membrane, and the electrons reach the cathode through an external circuit. The device has the advantages of high efficiency, low temperature, cleanliness and environmental protection.

[0003] In the proton exchange membrane fuel cell, the current collector plates are arranged at the upper and lower ends of the core to realize the positive and negative output of the current. However, the existing collector plate is in the form of a whole piece of metal plate, and its size is also the same as the cross-sectional area in the core, which is prone to the following probl...
