Introduction

Metal hydride hydrogen storage canister utilizes the selective absorbing ability of hydrogen storage alloys inside to absorb and desorb hydrogen under certain temperature and pressure. It has realized safe solid-state hydrogen storage without any leakage or energy lost. Our device has passed the appraisal of research achievement from CNMIA, and the overall technology has reached international advanced level.

Advantages

★ It has realized safe hydrogen absorption and desorption without any leakage or energy lost. Its hydrogen storage density can reach liquid hydrogen storage density.

★ It has the strength of low operation pressure, excellent safety and long life cycle. The storage volume could still be higher than 90% of its initial volume after 3000 absorption and desorption cycles.

★ It has the function of hydrogen purification, the purity of desorbed hydrogen is 99.9999%.

★ It is easy to operate. Hydrogen can be stored and released with smooth and steady airflow, which is suitable for the hydrogen source of portable equipment.

It adopts a unique thermal conductivity structure and alloy filling patent technology inside the canister, which accelerates the speed of hydrogen charging and discharging.

★ The hydrogen input/output pressure and flow rate can be controlled by adjusting the temperature.

Specification

According to different capacity and application, metal hydride hydrogen storage cylinder is divided into two kinds: hydrogen storage device for instruments and rapid hydrogen storage and supply devices. The first kind has the advantages of large hydrogen storage density, high hydrogen purity, good leakproofness and safety, small size and convenient to carry. It is especially suitable for the supporting hydrogen source of portable instruments such as fuel cell and gas chromatograph. According to different application requirements, we developed two types of tank, stainless steel and aluminum alloy, and they can be matched with two valves, needle valve and quick-connect valve.

Hydrogen Storage Device for Instruments—Needle Valve

According to customers' different requirements for the working pressure, this device can be divided into three types: high pressure (G-type), middle pressure (Z-type) and low pressure (D-type). G-type: working pressure range 0.1-3MPa, the hydrogen charging pressure is 3 MPa at most; Z-type: working pressure range 0.1-1.5MPa, the hydrogen charging pressure is 1.5MPa at most; D-type: working pressure range 0.1-0.7MPa, the hydrogen charging pressure is 0.7MPa at most. The D-type can be charged with hydrogen generator. According to customer requirements, the hydrogen output can be configured with a cutting ferrule (Photo 4), a thread or a quick-connect valve (Photo 5).



Hydrogen Storage Device for Instruments—Quick-Connect Valve

This device can be switched on and off by the connecting and disconnecting the quick-connect valve (Photo 6). According to customers' different requirements for the working pressure, it could be divided into two types: middle pressure (Z-type) and low pressure (D-type). Z-type: working pressure range 0.1-1.5MPa, the hydrogen charging pressure is 1.5MPa at most; D-type: working pressure range 0.1-0.7MPa, the hydrogen charging pressure is 0.7MPa at most. The D-type can be charged with hydrogen generator.
