Abstract

The invention discloses a modular passive direct alcohol fuel cell stack. Existing passive direct alcohol fuel cell stacks have a low level of integration and can not meet the requirements of relatively high voltage and high power applications for electrical equipment. The invention comprises n quadruplex batteries. The quadruplex battery comprises an electrical connection module, a polymer connection end plate and two battery cells. The quadruplex battery comprises an electrical connection module, a polymer connection end plate and two battery cells. The battery unit includes an anode polymerend plate, an anode electrode assembly, a cathode electrode assembly, a membrane electrode assembly, and a cathode polymer end plate. The anode electrode assembly and the cathode electrode assembly each include a rubber pad, a first collector, and a second collector. The anode polymer end plate, the anode electrode assembly, the membrane electrode assembly, and the cathode electrode assembly arearranged in order. The anode polymer end plates and the polymer connection end plates in the two battery cells are fixed on both sides respectively. A quadruple cell of the invention comprises a direct alcohol fuel cell with four common anodes, which has a compact structure, is easy to process and has high mechanical strength.

Description

technical field [0001] The invention belongs to the technical field of direct alcohol fuel cells, in particular to a modular passive direct alcohol fuel cell group. Background technique [0002] As an environmentally friendly portable energy source, direct alcohol fuel cell (DMFC) is more suitable as a new energy source for portable electronic products due to its advantages of miniaturization, high energy density, short response time and environmental protection. And compared to the active direct alcohol fuel cell, the passive direct alcohol fuel cell does not need to use active auxiliary equipment such as pumps and fans to supply fuel, and directly uses diffusion and natural convection effects to supply liquid to the battery, which greatly reduces The additional power output of the entire system facilitates integration as well as portable applications. Most of the current passive direct alcohol fuel cells are planar structures. Due to the limitation of space and structure,...
