Construction of Hydrogen Safety Evaluation Model Based on Analytic Hierarchy Process (AHP)

With the large consumption of traditional primary energy, hydrogen as a clean and renewable energy has been widely studied by scholars around world. Hydrogen is mainly used in internal combustion engine fuel cell. direct fuel, with advantages easy use. Alternatively, cell converts chemical into electrical electrochemical reaction, which high efficiency zero pollution. Regardless use method, safety needs to be considered. However, whole life cycle hydrogen, process from production automobiles extremely complex. There are many factors affecting use, single factor cannot an evaluation. In order make evaluation more complete accurate, weight four indexes eight secondary determined analytic hierarchy process, reliable model established.
