Abstract

The invention discloses a single-channel line-based hydrogen peroxide membrane-free passive microfluid fuel cell which comprises a cover plate, an anode electrode, a cathode electrode, a cotton threadrunner and a support plate. The microfluid fuel cell is characterized in that the anode electrode and the cathode electrode are arranged on the supporting plate in a bilateral symmetry mode, a gap isreserved between the anode electrode and the cathode electrode, and the cotton thread runner is placed on the anode electrode and the cathode electrode; the left part and the right part of the cottonthread runner are respectively overlapped with the cathode electrode and the anode electrode, and a certain height difference is set between an inlet and an outlet of the cotton thread runner; the cotton thread runner is a flow channel for fuel and electrolyte, the fuel and the electrolyte are conveyed to the surfaces of the anode electrode and the cathode electrode by the cotton thread runner, the fuel is hydrogen peroxide, and the cotton thread flow channel is made of a plurality of hydrophilic cotton threads; the single-strand cotton thread is adopted as a runner, passive transportation offuel and an oxidizing agent is achieved through capillary force or the capillary force coupling gravity effect, and the device can be widely applied to the fields of chemical engineering, energy, environmental protection and the like.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a single-channel line-based hydrogen peroxide membrane-free passive microfluidic fuel cell. Background technique [0002] In recent years, with the development of science and technology and the improvement of people's living standards, more and more mobile and portable electronic products have entered people's lives, and these electronic products have put forward an urgent need for miniaturized power supplies with high efficiency and high energy density. requirements. Currently common miniature portable mobile power sources include solar cells, lithium batteries, and miniature direct methanol fuel cells. Solar cells are greatly affected by the environment and weather and have low photoelectric conversion efficiency; lithium batteries have poor safety, high cost and cannot achieve continuous operation; and micro direct methanol fuel cells face water management problems, catalysts are ea...
