A microfluidic fuel cell with a separator membrane

Abstract

The invention discloses a microfluidic fuel cell with a separation membrane, comprising an upper cover plate, a lower cover plate, a cathode, an anode, an inlet plate and an outlet plate; it is characterized in that: the cathode, the anode, the inlet plate and the outlet plate are all Placed on the lower cover plate, located below the upper cover plate; the anode and the cathode are arranged opposite to each other on the left and right, and there is a gap between the cathode and the anode, which serves as the main channel for the solution to flow; the main channel is provided with a separation film , the separation membrane divides the main flow channel into left and right flow passages; the separation membrane is a porous filter paper or a nylon membrane prepared by an in-situ polycondensation chemical reaction synthesis method; the inlet plate and the outlet plate are respectively arranged at The front and rear sides of the main channel; the inlet plate is provided with two inlet channels, the output ends of the two inlet channels are respectively connected with the left and right flow channels of the main channel, and the outlet plate is provided with two outlet channels ; The present invention can be widely used in fields such as energy, etc.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a microfluidic fuel cell with a separation membrane. Background technique [0002] With the rapid development of science and technology, various high-performance mobile electronic devices (such as smart phones, micro-sensors, portable medical devices, etc.) The performance is continuously enhanced, and the requirements for power output power and continuous running time are getting higher and higher; on the other hand, electronic equipment is increasingly miniaturized and miniaturized, accompanied by the continuous reduction of battery volume. At present, these electrode devices mostly use lithium-ion batteries and other power sources. However, the energy density of these power supplies is low, which cannot meet the requirements of long-term continuous operation, and the output power of the battery is not too high. Micro direct methanol fuel cells are limited by issues such as difficul...

Problems solved by technology

[0004] The main problem with current microfluidic fuel cells is the anode CO 2 Effect of air bubbles on battery performance

As the electrochemical reaction continues, CO 2 The bubbles will continue to grow and coalesce, and fill the entire microchannel. During this process, the bubbles will greatly disturb or even destroy the parallel laminar flow, causing convective mixing of the oxidant and fuel, resulting in the penetration of fuel or oxidant, and generation of Parasitic current, causing a sharp drop in battery performance
