Abstract

The invention relates to a solar battery, and aims at providing a solar battery for staggered power generating in situ. The battery takes non-woven fabrics manufactured by an anion-exchange membrane or polypropylene fibre as a septum and takes aqueous alkali as electrolyte; the battery takes a conducting polymer modified carbon-based cobalt hydroxide catalyst loaded on an electrode matrix as an anode and takes a water splitting hydrogen storage material as a cathode. The water splitting hydrogen storage material includes a titanic type hydrogen storage alloy as a matrix and a membrane adhered on the surface of the matrix and consisting of anatase titan TiO2 and transition metal particles through mixing. The solar battery for staggered power generating in situ realizes the photoelectric conversion, but also can store power energy, and can implement staggered power generating in situ. Meanwhile, the solar battery for staggered power generating in situ changes the current situation that the traditional solar battery can only implement energy conversion, but can not implement energy storage, expands the application scope of the solar battery, and is one revolution for solar battery technology.

Description

technical field [0001] The present invention relates to a solar cell, in particular to a hydrogen storage material that can convert sunlight into hydrogen energy by photolysis of water and store it, and then convert the stored hydrogen energy into electrical energy in situ in the form of an air battery and release it. The hydrogen in the hydrogen material is consumed, and the sunlight can be used to photolyze water to store hydrogen, and it goes round and round, which is a new type of solar cell that continuously converts solar energy into electrical energy. Background technique [0002] With the development of the world economy and the improvement of people's living standards, limited natural resources such as coal, oil, and natural gas can no longer meet the needs of human development. Solar energy has incomparable advantages: clean, inexhaustible, and available all over the world. Therefore, the development and utilization of solar energy are increasing year by year. So...
