The invention belongs to the technique of producing hydrogen with solar energy. The invention mainly contains parabolic mirror plane heat collecting plate, turbine (generator), accumulator, water electrolyzer. The water is heated to boiling point, vapor pushes the aerorbiculus generator, electric energy is stored in the electric bottle which supply electric to the water electrolyzer, heating the water to 80DEG C and adding industrial grade hydrogen peroxide 0.03-0.05wt%, electrolyzing water to separate hydrogen. The invention has the advantages of simple equipment structure, simple installation, low cost, good technology, high hydrogen purity, and easy production.
