Abstract

The invention relates to a microfluid-based self-breathing photocatalytic film-free fuel battery. The microfluid-based self-breathing photocatalytic film-free fuel battery is characterized in that conductive glass, a microfluid battery chip and a gas dispersing electrode form a main body of the micro-flow photocatalytic film-free fuel battery; the conductive glass is loaded with a titanium dioxide semiconductor nanorod serving as a photocatalyst; an anode conductor and a cathode conductor are used for leading out electric energy generated from the interior of the battery for external electric appliances to use; and organic waste water pollutant and anode electrolyte respectively flow in from an anode liquid inlet and a cathode liquid inlet. The microfluid-based self-breathing photocatalytic film-free fuel battery removes a proton exchange membrane required by a traditional photocatalytic fuel battery by a principle of laminated flow of microfluid laminar flow so as to simplify the battery structure and reduce the manufacturing cost; oxygen of air enters the battery chip through the gas dispersing electrode to participate in reaction without a special conveying device; and the waste water pollutant and the anode electrolyte are injected into the photocatalytic fuel battery chip through a micro-flow pump, and chemical energy of the organic pollutant is transformed into electric energy which is output outwards.

Description

【Technical field】 [0001] The invention relates to the technical field of fuel cells, in particular to a microfluid-based self-breathing photocatalytic membraneless fuel cell. 【Background technique】 [0002] The photoelectrochemical reaction is to use light energy as energy input to promote the electrochemical reaction, so that the chemical energy stored in the chemical substance is converted into electrical energy and output. [0003] When the photocatalyst in the photocatalytic fuel cell is irradiated by light radiation, the semiconductor photocatalyst is excited, releasing electrons and generating holes at the same time. The released electrons and holes can react with water to generate strong oxidizing free radicals, which can decompose organic pollutants in wastewater. The electrons generated by excitation can also be exported through the external circuit to form a current to supply power to the external circuit. [0004] The current photocatalytic fuel cell adopts a bu...
