Problems solved by technology

[0008] Aiming at the problems in the prior art, the present invention provides an all-weather and fast-response solid-state hydrogen storage fuel cell power system. In this system, the solid-state hydrogen storage device not only has a higher weight hydrogen storage rate, but also meets the needs of fuel cell vehicles. At the same time, through the system design, it can also meet the safe use requirements at the highest temperature rise and pressure, meet the cold start requirements of fuel cell vehicles, and avoid the reverse absorption of hydrogen storage materials in the system when fuel cell vehicles stop halfway. Hydrogen, further exacerbating the emergence of cold start problems of hydrogen storage systems

Embodiment 1

[0040] The power system of the present invention is subjected to a high temperature simulation environment test. First, charge the solid-state hydrogen storage device for the experiment to 3MPa at room temperature (20°C). After the air pressure is stabilized, heat it with circulating antifreeze and raise the temperature to 30°C. Observe the internal pressure change through the pressure gauge. After the pressure is stable, raise the temperature to 40°C. ℃, after the pressure is stable, continue to heat up to 50℃, the pressure in the solid state hydrogen storage device changes with temperature as follows: figure 2 As shown in the middle curve, the internal pressure of the solid-state hydrogen storage device is increased to 5.412MPa at 30°C, increased to 8.446MPa at 40°C, and increased to 11.812MPa at 50°C.

[0041] Then connect the solid-state hydrogen storage device and the multi-functional gas storage tank in series, charge hydrogen to 3MPa at room temperature (20°C), put the...

Embodiment 2

[0044] The power system of the present invention is subjected to a high temperature simulation environment test. Firstly, the experimental solid-state hydrogen storage device and the multi-functional gas storage tank are connected in series, and a one-way valve is added in between. Charge hydrogen to 3MPa at room temperature (20°C), cool down with low-temperature circulating antifreeze after the air pressure is stable, and measure the internal pressure changes of the solid-state hydrogen storage device and the multi-functional gas storage tank through two pressure gauges. Due to the existence of the check valve, when the air pressure drops, the hydrogen in the multi-functional gas storage tank will not flow into the solid-state hydrogen storage device in reverse, that is, during this process, the pressures in the solid-state hydrogen storage device and the multi-functional gas storage tank are relatively independent. Cool down to 10°C, then cool down to 0°C after the pressure ...

Abstract

The invention discloses an all-weather quick-response solid hydrogen storage fuel cell power system, which comprises a solid hydrogen storage device, a multifunctional gas storage tank and a fuel celldevice, and is characterized in that the fuel cell device comprises a hydrogen pipeline, a fuel cell, a circulating water pump, a cold water pipeline and a hot water pipeline; one end of the multifunctional gas storage tank is connected with the solid hydrogen storage device through a pipeline provided with a one-way valve, the other end of the multifunctional gas storage tank is connected with the fuel cell through a hydrogen pipeline, and an electromagnetic valve is installed on the hydrogen pipeline. The fuel cell is connected with the solid hydrogen storage device through a cold water pipeline and a hot water pipeline; and during starting, the fuel cell is started firstly, and then the electromagnetic valve is opened, so that hydrogen flows into the fuel cell from the solid hydrogen storage device through the one-way valve and the multifunctional gas storage tank. The stability of a hydrogen source can be improved, reverse hydrogen absorption of the solid hydrogen storage device is prevented, the wall thickness of the tank body is reduced, and the weight hydrogen storage density is improved.
