Problems solved by technology

Metal hydrogen storage is used. Most hydrogen storage alloys are heavy in weight, short in life, easy to poison, and the hydrogen storage capacity cannot meet the practical requirements.
At present, the following main problems still exist in the hydrogen storage of carbon nanotubes: ①The gaseous hydrogen storage pressure of carbon nanotubes is too high, there is no hydrogen absorption and desorption platform area, and the hysteresis of hydrogen absorption and desorption is relatively large
② Carbon nanotube electrochemical hydrogen storage has low electrocatalytic activity, large self-discharge and low hydrogen storage capacity
It can be seen that the defects of the current hydrogen storage materials are difficult to fully meet the conditions of large hydrogen storage capacity, operable hydrogen absorption / desorption at room temperature, easy activation, small hysteresis effect, strong anti-poisoning ability, and low material cost. application requirements, so there is no ideal hydrogen storage and transportation method at this stage, and it will be used in vehicles and other mobile tools in the foreseeable future

And it can be used in vehicle loading fuel cell or hydrogen supply in other field.

Description

Technical field: [0001] The invention relates to a hydrogen storage material, in particular to a polystyrene metal cross-linked resin hydrogen storage material. Background technique: [0002] Hydrogen energy is clean, renewable, portable, and fast-filling, making it an ideal fuel for fuel cells. As an ideal alternative energy source, hydrogen energy is receiving extensive attention and research from all over the world. A key link in the utilization of hydrogen energy is the storage and transportation of hydrogen, because hydrogen is difficult to liquefy, and its critical point is 33k, which makes storage and transportation difficult. Therefore, at present, high-pressure hydrogen storage and low-temperature liquid hydrogen storage are mostly used. For an ordinary car, the pressure of the hydrogen needed to travel 300 kilometers in a 60-liter container is about 700 kilograms! Safety concerns arising from such high pressures have long been a concern. The space occupied by l...
