Description:

During the operation of a fuel cell system, the electrochemical reaction on the cathode side of the stack produces a large amount of liquid water. This water is discharged together with the exhaust gas, forming a gas-liquid two-phase flow. If the exhaust gas carrying a large amount of liquid water directly enters the air compressor expander (turbine), the high-speed water droplets will impact the expander impeller, causing impeller erosion and mechanical damage, and reducing the expander's energy recovery efficiency, further affecting the power output and service life of the entire fuel cell system. Therefore, before the exhaust gas enters the expander, the gas-liquid two-phase flow must be efficiently separated.

The MANN+HUMMEL cathode water separator is a key BOP component designed precisely to solve this problem. The product uses the inertial separation principle: when the gas flow containing droplets passes through the optimized simulated flow channel, the centrifugal force and inertial force generated by the high-speed movement of the gas cause the denser droplets to hit the channel wall and be captured and collected. The separated liquid water is discharged from the system through the continuous drainage mechanism, while the dry exhaust gas continues to flow to the expander for energy recovery. Through this process, the product simultaneously achieves two core functions: protecting the downstream expander from water hammer damage, and ensuring the exhaust gas is dry to guarantee efficient energy recovery by the expander, thereby improving the overall efficiency of the fuel cell system.

Through an optimized simulated flow channel design, the MANN+HUMMEL water separator achieves efficient gas-liquid separation while maintaining low pressure loss. The product can be applied to multiple positions on the anode and cathode of a fuel cell system. Through a standardized design it enables fast selection and matching for customers, and can also be adapted and developed according to the customer's boundary conditions.

MANN+HUMMEL is a leading company in the field of fuel cell BOP (Balance of Plant). The product provides three performance grades, MEDIUM, HIGH and HIGH+, adapting to 30~60kW, 80~150kW and 150~200kW fuel cell systems respectively. It supports both vertical and horizontal installation and can be tilted up to +/-20 degrees, providing great flexibility for system integration. The product adopts a compact package optimization design, saving installation space while ensuring high performance.

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

Q4: Why does a fuel cell system need a cathode water separator?
A: The cathode side reaction of the fuel cell stack produces a large amount of liquid water, which is discharged together with the exhaust gas. If the exhaust gas carrying a large amount of liquid water directly enters the air compressor expander, the high-speed water droplets will impact and erode the expander impeller and reduce the expander's energy recovery efficiency. The role of the cathode water separator is to efficiently separate and discharge the liquid water before the exhaust gas enters the expander, protecting the expander and ensuring energy recovery efficiency.

Q5: What is the working principle of the cathode water separator?
A: The MANN+HUMMEL cathode water separator uses the inertial separation principle: when the gas flow containing droplets passes through the optimized simulated flow channel, the centrifugal force and inertial force generated by the high-speed movement of the gas cause the denser droplets to hit the channel wall and be captured and collected. The separated liquid water is discharged from the system through the continuous drainage mechanism, and the dry exhaust gas continues to flow to the expander for energy recovery.

Q6: What performance grades does the WaterPro series have?
A: The WaterPro series provides three performance grades: MEDIUM (30~60kW), HIGH (80~150kW) and HIGH+ (150~200kW).

Q7: What is the pressure loss of the cathode water separator?
A: The pressure loss is about 3~5kPa @ customer-specified conditions; the specific value depends on the flow rate and installation method.

Q8: What installation methods does the cathode water separator have?
A: It supports both vertical and horizontal installation and can be tilted up to +/-20 degrees, providing great flexibility for system integration.

Q9: Does the cathode water separator have an anti-freeze function?
A: Yes, the product is designed to be anti-freeze and can operate reliably in low-temperature environments.

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.
