Fuel Cell System Exhaust Muffler 30-300kW Insertion Loss Over 21dB Low Back Pressure Design

Fuel Cell System Exhaust Muffler for 30~300kW Systems Insertion Loss Over 21dB Low Back Pressure Design

Quick Detail:

• Muffler developed specifically for the tailpipe system of proton exchange membrane fuel cell (PEMFC)
• Applicable power range: 30~300kW (covering commercial vehicles, stationary power stations and other scenarios)
• Insertion loss: >21dB, with obvious noise reduction effect
• Effective silencing frequency band: 1000~10000Hz, specially optimized for wide-band high-frequency exhaust noise
• Exhaust back pressure: <=5kPa @ maximum flow (room temperature)
• Low exhaust back pressure, good corrosion resistance
• Features drainage and hydrogen dilution functions
• Working temperature range: -40C ~ 100C
• Meets air tightness requirements: <=3L/min @ 30kPa

Description:

When a fuel cell system is working, air is pressurized by the air compressor and enters the stack to participate in the reaction, and the reacted exhaust gas is discharged through the tailpipe. Due to the high-speed operation of the air compressor and the high-speed gas flow, the fuel cell tailpipe noise has the characteristics of a wide frequency band and high frequency. Without effective treatment, the high-intensity wide-band noise will seriously affect the ride comfort of the vehicle and the surrounding environment. The XK series/EY series tailpipe muffler is developed precisely for this pain point and is a core component for optimizing the NVH performance of the fuel cell system. The product achieves efficient noise reduction while maintaining extremely low exhaust back pressure and excellent corrosion resistance. At the same time, the muffler also features drainage and hydrogen dilution functions, meeting the comprehensive needs of the fuel cell system tailpipe.

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: Why does a fuel cell system need a tailpipe muffler?
A: Fuel cell tailpipe noise has the characteristics of a wide frequency band and high frequency. Without effective treatment, the high-intensity wide-band noise will seriously affect the ride comfort of the vehicle and the surrounding environment. The tailpipe muffler can effectively improve the NVH performance of the fuel cell system through targeted noise reduction design.

Q5: How effective is the muffler noise reduction?
A: The muffler insertion loss exceeds 21dB, with good silencing effect in the 1000~10000Hz wide frequency band, specially optimized for the wide-band high-frequency noise of fuel cells.

Q6: What power fuel cell systems does the muffler fit?
A: The muffler can match 30kW~300kW fuel cell systems.

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.
