Ultra-pure water membrane electrolyser

Abstract

An ultra-pure water membrane electrolyser belongs to the technical field of electrolytic cell, comprising an anode clamping plate, an anode current collector, a membrane electrode, a sealing gasket, a cathode current collector and a cathode clamping plate; wherein, the electrolyser is characteristics in that: the anode clamping plate thereon is provided with a horizontal groove flow field, a sealing ring, a water inlet, a water outlet and a fastening bolt hole. The anode clamping plate not only locates and fastens the electrolytic cell, but also has the flow field function of channelizing water and oxygen flowage. The anode current collector transmits the electric energy of an external power to an anode catalytic layer on the surface of the membrane electrode to realise electrochemical oxidization of water, so as to generate oxygen and hydrogen ion. The cathode current collector transmits the electric energy of the external power to a cathode catalytic layer on the surface of the membrane electrode to reduction of hydrogen ion, so as to generate hydrogen. The cathode clamping plate thereon is also provided with a flow field, a sealing ring, a water outlet and a fastening bolt hole, and the components are assembled in sequence and then fastened by screw rods and nuts. The electrolyser has the advantages as follows: simple structure, high working efficiency and long service life.

Description

technical field [0001] The invention relates to the technical field of electrolytic cells, and in particular provides an ultrapure water membrane electrolysis device. Background technique [0002] Energy and the environment are the basis for human survival and development. With the increasingly serious fossil energy crisis and environmental pollution, it is imminent to develop clean new energy and renewable energy. Hydrogen energy is recognized as a clean and efficient energy source. It has a wide range of sources and is extremely rich in resources. It is the most promising alternative to fossil energy in the future. In recent years, countries around the world have formulated hydrogen energy development plans and corresponding plans, and invested a lot of money to support hydrogen energy development and application demonstration activities. To realize the widespread application of hydrogen energy, the following three major problems need to be solved: the preparation of a l...
