Abstract

The invention discloses a test system for hydrogen production by hydrolyzing complex metal hydride in water vapour. The test system comprises a gas circuit system and a measurement-control system, so that the dehydrogenation rates and the productivities of different complex metal hydrides during hydrolyzing in water vapour with different accelerators and catalysts can be evaluated and consequently the formulas of a low-cost hydrogen storage material and a water vapour hydrolytic agent which meet the development requirement of a fuel cell vehicle can be selected. The test system comprises a high-pressure gas cylinder, a pressure reducing valve, a filter, a ball valve, a flowrate control meter, a check valve, a water tank, a plunger pump, an evaporator, a coil, a heating cable, a hydride reaction bed, an electric furnace, a low-temperature water bath, a gas chromatograph, a gas dryer, a temperature control instrument, a temperature measuring instrument, a computer, a data acquisition and control device, control software and the like. The whole data control process is finished by the control software in accordance with relevant computing methods. The test system has the advantages ofexcellent human-machine operation interface, convenience and simplicity for operation, high testing efficiency, low cost, high test data accuracy, high repeatability and the like.

Description

technical field [0001] The invention relates to the field of evaluation of hydrogen production performance of hydride materials, in particular to a test system for hydrogen production by steam hydrolysis of complex metal hydrides. Background technique [0002] With the gradual depletion of fossil energy and the deterioration of the global environment, people are paying more and more attention to green new energy technologies. Hydrogen energy has many advantages, including high combustion calorific value, the combustion product is water, clean and clean, rich in resources, and can be produced from water to realize the recycling of natural materials. At present, countries are competing to research hydrogen-powered fuel cell vehicle technology, but one of the technical bottlenecks is how to obtain a hydrogen storage system that meets the vehicle's operating requirements. For this reason, the U.S. Department of Energy (DOE) has formulated a very strict FreedomCAR plan for hydro...
