• Design life: >40000 hours; Installation: compact and miniaturized design, installed at the end of the tail hydrogen discharge

Description:

During operation of a fuel cell system, the hydrogen utilization rate is usually 90~95%, and still 5~10% of hydrogen is discharged during startup purge, operation and shutdown. This hydrogen-containing off-gas is usually mixed with excess air and discharged into the atmosphere, but in enclosed spaces (such as underground parking lots, warehouses, cold storage, tunnels, underwater environments, etc.), hydrogen, due to its extremely light characteristics (density 1/14 of air), will stratify and accumulate at the top of the space; after long-term accumulation it may reach the explosion limit, creating an explosion risk.

The HOGE hydrogen off-gas elimination assembly is an innovative product developed precisely to solve this safety hazard. Through a high-efficiency catalyst supported on a special substrate, it catalytically reacts the low-content hydrogen in the fuel cell hydrogen-containing off-gas with excess oxygen to form water; the reaction product is only water, environmentally friendly and safe. The product is compact and can be installed at the end of the tail hydrogen discharge, requiring no external heat source heating, and can work normally in ambient or low-temperature environments.

The core advantages of the HOGE dehydrogenation device include:

No external heat source required, wide application range: the product can work normally within a wide temperature range of -30C~200C without external heat source heating. The low-temperature type can start the dehydrogenation reaction under ambient conditions; the high-temperature type starts under high-temperature off-gas conditions of >=130C.

High catalytic efficiency and low flow resistance: catalytic efficiency up to more than 95%, working pressure drop <2kPa, with minimal impact on system back pressure. The hydrogen removal lower limit is <10ppm for the low-temperature type and <100ppm for the high-temperature type, ensuring safe off-gas discharge.

Ultra-long life: design life >40000 hours, meeting the full life cycle use requirements of fuel cell systems.

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: 3-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: Why does a fuel cell system need a hydrogen-containing off-gas elimination device?
A: A fuel cell discharges about 5~10% of hydrogen during startup purge, operation and shutdown. In open spaces hydrogen diffuses quickly with no safety hazard; but in enclosed spaces (underground parking lots, warehouses, cold storage, tunnels, etc.) hydrogen stratifies and accumulates at the top due to its low density and creates an explosion risk once the explosion limit is reached. The HOGE dehydrogenation device converts hydrogen into water through a catalytic reaction, eliminating this safety hazard.

Q5: What is the working principle of the HOGE dehydrogenation device?
A: It uses the catalytic oxidation principle: through a high-efficiency catalyst supported on a special substrate, the low-content hydrogen in the fuel cell hydrogen-containing off-gas and excess oxygen are catalytically converted into water (2H2 + O2 -> 2H2O); the reaction product is only water, environmentally friendly and safe.

Q6: What is the catalytic efficiency of the HOGE dehydrogenation device?
A: Catalytic efficiency up to more than 95%.

Q7: What is the working temperature range?
A: Applicable temperature range -30C~200C.

Q8: What is the design life of the HOGE dehydrogenation device?
A: Design life >40000 hours.

Q9: 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.
