Description:

During operation, a fuel cell engine takes the oxygen used as oxidant from the ambient air pressurized by the air compressor. However, ambient air contains not only dust particles but also harmful polluting gases (mainly SO2, NOx and NH3) that permanently poison the fuel cell stack catalyst. Without effective purification, these impurities will directly cause stack performance degradation and a greatly shortened service life. This series of cathode air filters is designed precisely to solve this pain point, and is the core purification component that guarantees long-term stable operation of the fuel cell system.

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: How to determine when the filter element needs to be replaced?
A: Refer to the user manual or maintenance manual of the fuel cell system you are using. It can also be judged by monitoring the pressure difference between the inlet and outlet of the filter element; when the pressure difference is too large, it indicates the filter element is clogged and needs to be replaced.

Q5: What are the competitive advantages of your product over other brands?
A: Our filter media formula is specially optimized for the cathode characteristics of fuel cells. The adsorption capacity for SO2 and NOx is more than 30% higher than ordinary industrial filters, and the initial resistance is lower, which can effectively reduce the parasitic power consumption of the air compressor.

Q6: Can the customer LOGO be printed on the product?
A: Yes. Before mass production, please formally inform us and provide the LOGO design file; we can assist with housing silk-screen printing or label customization.

Q7: 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.
