Ultrasonic fuel cell

Abstract

The invention relates to an ultrasonic fuel cell, which includes a front end plate, a rear end plate, an electric pile formed by stacking up and combining a plurality of single batteries in series, and a screw rod. The electric pile is arranged between the front end plate and the rear end plate and is fastened and fixed by the screw rod. Each single battery is formed by stacking a bipolar plate, carbon paper / carbon cloth, a catalyst sheet layer, a proton exchange membrane, a catalyst sheet layer, carbon paper / carbon cloth and a bipolar plate in sequence. A plurality of ultrasonic transducers are arranged on the outer side of the single battery and positioned on the back surface of the bipolar plate. Each ultrasonic transducer is connected with an electric wire. High-frequency ultrasonic vibration is generated when the ultrasonic transducer works. In this way, impurities generated in the fuel reaction process are prevented from precipitating on the fluid channel, the carbon paper / carboncloth, the catalyst sheet layer, the proton exchange membrane and the like to cause blockage. The passivation of the fuel cell is greatly delayed. The electric energy conversion efficiency of the fuel cell is improved. The service life and the reliability of the fuel cell are greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of new energy utilization, in particular to a fuel cell. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth new power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is very high. In addition, the fuel cell uses fuel and oxygen as raw materials, and has no mechanical transmission parts, so there is no noise pollution, and the harmful gas emitted is very small, almost negligible. From the perspective of saving energy and protecting the ecological environment, fuel cells are the most promising power generation technology. [0003] F...
