System and method for safely eliminating hydrogen through normal-temperature hydrogen-oxygen reaction based on Pt-based catalyst

The invention provides a normal-temperature hydrogen-oxygen reaction system and method based on Pt-based catalysis, which are used for safely eliminating hydrogen in a limited space under a normal-temperature condition. The closed reaction chamber is provided with a catalyst filling area and is provided with a hydrogen concentration sensor, a temperature sensor and a pressure sensor; the filtering device is mounted at the gas inlet and used for filtering impurities in reaction gas, and is mounted at the gas outlet and used for gas-liquid separation; the controller comprises a temperature sensor, a gas flow controller and a microprocessor and is used for monitoring and adjusting the flow of hydrogen and air in real time; the safety valve is used for releasing gas in the reaction chamber when abnormity is detected. The system can maintain stable reaction conditions in a normal-temperature environment, and the hydrogen conversion rate and the operation safety are remarkably improved by adjusting the flow and the
