Description:

The proton exchange membrane in a fuel cell stack needs a humid environment to maintain optimal proton conductivity. The GZS series humidifier uses hollow fiber membrane technology, using special materials to make membrane tubes, forming independent dry/wet channels inside and outside the tubes. The working principle is as follows: dry air from the air compressor enters the inside of the membrane tubes (dry side) from one end of the humidifier, and the high-temperature high-humidity exhaust gas discharged by the stack enters the outside of the membrane tubes (wet side) from the other end. By recovering water and heat from the stack exhaust, heat-moisture exchange is performed on both sides of the membrane wall, thereby heating and humidifying the dry air to the temperature and humidity required by the stack.

The humidifier product line covers two series:

General series: GZS05, GZS15, GZS30, GZS60, GZS80, GZS120, GZS150, GZS180, for 5~200kW fuel cell systems;

Integrated series: J05, J20, J60, J80, J120, J150, J180, etc. The integrated series highly integrates the humidifier and the intercooler into one unit, and can effectively integrate the intercooler and the throttle valve on the basis of the humidifier, greatly saving system space, reducing piping connections and lowering system cost; customized development requirements are accepted.

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

Q4: What is the working principle of the humidifier?
A: The humidifier uses hollow fiber membrane technology, forming independent dry/wet channels inside and outside the membrane tubes. Dry air from the air compressor enters the inside of the membrane tubes, and the high-temperature high-humidity exhaust gas discharged by the stack enters the outside. By recovering water and heat from the stack exhaust, heat-moisture exchange is performed on both sides of the membrane wall, bringing the dry air to the temperature and humidity required by the stack.

Q5: What are the working temperature and pressure ranges of the humidifier?
A: Dry-side working temperature -40C~85C, wet side -40C~95C; maximum working pressure 3.5 bara; maximum membrane pressure difference (inside to outside) 110kPa.

Q6: How efficient is the humidifier?
A: Humidification efficiency is expressed as the approach to the dew point, reaching 5~17C for gas-to-gas humidification. Taking GZS120 as an example, at a dry air outlet temperature of 70C the humidity is >60%RH @ 7,000sLPM.

Q7: How is the humidifier installed?
A: Both inverted and flat placement are acceptable; horizontal flat placement is recommended for easy connection. The inlet and outlet clamps are recommended to be tightened at 3.5N.m. Tightening the overall plastic part with a clamp exceeding 20N.m will damage the body.

Q8: 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.
