Photovoltaic and water electrolysis hydrogen production integrated device

Abstract

This invention discloses an integrated photovoltaic and water electrolysis hydrogen production device, comprising a photovoltaic power generation module, an electrolysis hydrogen production module, an intelligent matching control module, a waste heat recovery module, and an integrated support shell. The photovoltaic power generation module is installed on the top outer surface of the integrated support shell and is used to convert solar energy into direct current. It employs a wide-width anion exchange membrane and a high-efficiency nickel-based composite catalyst, and the electrolyzer's operating current density can reach 100-1000 mA / cm². 2 It can be flexibly adjusted within a certain range, with a hydrogen evolution overpotential as low as 1.2V and high hydrogen production efficiency; at the same time, it achieves efficient separation of hydrogen and oxygen and deep drying of hydrogen through corrugated plate separation and molecular sieve drying, producing hydrogen with a purity of ≥99.99% and a water content of ≤10ppm, meeting the needs of industrial and civilian hydrogen energy applications.
