Abstract

The invention discloses an array tube type auto-respiration direct methanol fuel battery system which comprises a base board, a battery pack and an operating system thereof, wherein the battery pack comprises a plurality of single battery modules; the single battery modules sequentially comprise a cathode board layer, a cathode diffusing layer, a film electrode, an anode diffusing layer and an anode board layer from outside to inside; and penetrating holes are uniformly distributed on the circumferential wall of the anode board layer. In the system, an integral design idea is adopted; the installation and the connection of each single battery, the output of stable voltage and a parameter monitoring function are integrally designed on a PCB (Printed Circuit Board) motherboard through innovation and modular design on a single battery structure; and the direct methanol fuel battery system with the advantages of convenience for assembly, compact structure, integrated function, flexible power design and high specific power is realized.

Description

technical field [0001] The invention relates to the field of clean energy, in particular to an array tube type self-breathing direct methanol fuel cell system. Background technique [0002] As a low-pollution and high-efficiency power generation device without combustion process, fuel cell is the fourth generation main power generation technology in the future of the 21st century. Passive direct methanol fuel cell (DMFC) is especially suitable as a mobile or portable power source for various purposes due to its simple system structure, high volumetric energy density, reliable operation, and convenient fuel replenishment. DMFC with a tubular structure has unique advantages in portable power sources due to its advantages such as larger electrode reaction area than flat plate type and simple sealing. [0003] In recent years, there have been research reports on tubular direct methanol fuel cells at home and abroad. The literature shows that foreign research mostly focuses on t...
