Abstract

The invention discloses a structure facilitating cooling of fuel cells. The structure comprises a plurality of elementary cells in a fuel battery as well as an upper fixing plate and a lower fixing plate which are used for fixing the elementary cells, wherein a plurality of mutually parallel grooves A allowing arrangement of the elementary cells are formed in the upper fixing plate and the lower fixing plate; the interval between adjacent grooves A is one third of the thickness of each elementary cell; the plurality of elementary cells are connected through an oxygen inlet channel and a hydrogen outlet channel; a storage trough surrounding the elementary cells is connected onto the lower fixing plate; a connecting plate for being nested into the storage trough is connected onto the upper fixing plate; through grooves are formed in the upper fixing plate and the lower fixing plate, grooves B are formed between the connecting plate and each groove A, between the storage trough and each groove A as well as between every two adjacent grooves A, and one end of each groove B is in through connection with the corresponding through groove.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a structure for facilitating heat dissipation of the fuel cell. Background technique [0002] After nearly 20 years of rapid development, proton exchange membrane fuel cell technology has made great progress and successfully solved many problems. However, in order to realize proton exchange membrane fuel cells, there are still problems such as low volume specific power, thermal safety problems caused by reaction heat, and high cost, which limit its commercialization in electric vehicles and other fields. [0003] Fuel cells are more and more loved and used by people because of their high energy conversion efficiency, low noise, low carbon, zero emissions, flexible and convenient use, low operating temperature, and high energy density. Fuel cells are mainly divided into five major categories: phosphate fuel cell (PAFC), proton exchange membrane fuel cell (PEMFC), alkaline fuel cell (AFC), molten ca...
