Description:

The QQ-TMC series metal hydride hydrogen storage cylinder is filled with a hydrogen storage alloy material (MH: Metal Hydride), which has the unique characteristic of reversibly absorbing and releasing hydrogen at ambient temperature and low pressure. Compared with traditional high-pressure gaseous hydrogen storage (35~70MPa), the QQ-TMC series works at only <=3.5MPa, fundamentally eliminating the risk of high-pressure explosion.

Solid-state hydrogen storage is intrinsically safe: hydrogen is stored in the alloy lattice in the form of a solid hydride, and still will not release and explode over a large area even after bullet impact and burst testing; the principle of hydrogen release by the hydrogen storage alloy is completely different from high-pressure/liquid storage. Even if the external piping or equipment leaks, hydrogen is released gently at the working temperature of the hydrogen storage alloy rather than released instantaneously over a large area. This characteristic gives the QQ-TMC series an irreplaceable safety advantage in close-range hydrogen use scenarios such as micro-mobility and portable instruments.

FAQ

Q1: Can you provide samples for testing?
A: Yes, we support sample orders for vehicle installation testing and performance verification, and also accept mixed-model sample orders.

Q2: What is the delivery lead time?
A: Sample orders usually take 5-7 working days; bulk orders (depending on order quantity) generally take 15-30 working days.

Q3: Is there a minimum order quantity (MOQ) limit?
A: There is no strict MOQ limit; 10-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: What scenarios are the various QQ-TMC models suitable for?
A: QQ-TMC-20g (0.39L) suits small portable devices and hydrogen health products; QQ-TMC-50g/70g (0.9L/1.2L) suit hydrogen two-wheelers and scooters; QQ-TMC-85g/110g (1.55L/2L) suit hydrogen tricycles, logistics delivery vehicles and small fuel cell power supplies. One storage cylinder can store 100g of hydrogen with a range of about 100 km.

Q5: What is the difference between a solid-state storage cylinder and a high-pressure cylinder?
A: The solid-state cylinder works at <=3.5MPa, far lower than the 35~70MPa of a high-pressure cylinder. Hydrogen is stored in the alloy lattice in the form of a solid hydride and will not release and explode over a large area even after bullet impact and burst testing; even if the external piping leaks, hydrogen is released gently rather than instantaneously. In addition, the solid-state cylinder purifies hydrogen and can output 99.9999% ultra-high purity hydrogen.

Q6: How does the solid-state cylinder work with the fuel cell system?
A: The solid-state cylinder can be coupled with the waste heat of the fuel cell thermal management system for heated hydrogen release. The heat generated during fuel cell operation is transferred to the storage cylinder through the thermal management system; when the temperature of the hydrogen storage alloy rises, it releases hydrogen to be supplied directly to the fuel cell, achieving efficient utilization of system heat.

Q7: What valve types are available for the QQ-TMC series?
A: Four valve types: 1. automatic integrated with pressure reduction (electric heating / no heating): charging port is a built-in thimble 8mm quick connector, discharge port is an 8mm or 9mm quick connector, and the electrical interface is an automotive-grade waterproof 4-pin quick connector; 2. manual integrated with pressure reduction: both charge/discharge ports are 8mm quick connectors; 3. snap-in type: charge/discharge port is a 10mm built-in thimble snap-in quick male connector; 4. without pressure reduction: charge/discharge port is an SAE 7/16-20UNF female thread.

Q8: How long does charging take?
A: Charging time for all models is <=60 minutes. The specific charging time is affected by the cooling water temperature and charging pressure, and must be operated strictly according to the "Technical Regulations for Storage Cylinder Charging".

Q9: What is the service life of the product?
A: After 2000 charge/discharge cycles, the hydrogen storage capacity remains above 80% of the initial capacity. The designed life meets the full life cycle use requirements of micro-mobility and fuel cell systems.

Q10: How to handle product failures?
A: We implement a strict quality control system, with an out-of-factory defect rate below 0.2%. During the warranty period, small batches of defective products will be replaced with new ones in the next order; batch quality problems will be negotiated for repair or replacement to ensure customer rights.
