Description

technical field [0001] The invention belongs to the hydrogen energy production technology, and specifically relates to a photoelectric coupling dual-source excitation splitting water hydrogen production reactor, system and method. Background technique [0002] The petrochemical fuel is about to be exhausted, and as the main energy source in the 21st century, hydrogen energy will gradually replace the traditional petrochemical energy and become the main energy industry. Hydrogen energy is not only mainly used in direct combustion (aerospace), as a raw material for fuel cells, but also can be stored as the ultimate energy source. In particular, the fluctuating green power resources such as wind power and photovoltaic power that are affected by seasonal factors are efficiently converted into green hydrogen resources that can be stored for a long time. At present, the high conversion rate of fuel cell 60-70% has established it as one of the mainstays of the fourth generation en...
