Description:

In a fuel cell system, hydrogen coming out of the storage cylinder is usually at a low temperature (about -40C~40C), while the working temperature inside the stack is usually 60C~80C. Low-temperature hydrogen directly entering the stack not only affects the efficiency of the catalytic reaction but may also cause local condensation inside the stack, affecting the membrane electrode performance and service life. Therefore, preheating the hydrogen before it enters the stack is a key step to improving the efficiency and durability of the fuel cell system.

The K series standard brazed plate heat exchanger is a cost-effective solution designed precisely for this. It uses the heated high-temperature coolant (usually 60C~80C) in the fuel cell cooling circuit as the heat source to heat the low-temperature hydrogen before it enters the stack, raising the hydrogen temperature close to the stack working temperature before it enters the stack, thereby significantly improving the stack catalytic reaction efficiency, reducing system energy consumption and extending stack service life.

The K series uses a brazing process, in which the plates are vacuum-brazed to form a firm channel structure that can withstand relatively high working pressure. The plates use a unique herringbone corrugated design, which makes the cold and hot fluids produce strong turbulence in the channel, achieving efficient heat exchange. The plate material is SUS316/SUS304 stainless steel, ensuring long-term reliable operation in a hydrogen environment. In terms of ports, the K series offers three customizable connector types to meet the installation needs of different systems:

Female thread connector (standard product): threaded connection, suitable for high-pressure metal piping;

Quick connector: enables quick plug and unplug, convenient for installation and maintenance;

Bamboo connector: suitable for silicone hose connection, locked and sealed by a hose clamp;

Ferrule tube connector: suitable for ferrule connection, with reliable sealing, suitable for high-pressure hydrogen applications.

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 hydrogen heat exchanger?
A: The hydrogen from the storage cylinder is at a low temperature (-40C~40C), while the stack working temperature is 60C~80C. Low-temperature hydrogen directly entering the stack affects the catalytic reaction efficiency and may cause local condensation. The hydrogen heat exchanger uses coolant heat to preheat the hydrogen, significantly improving reaction efficiency and system durability.

Q5: What is the working principle of the hydrogen heat exchanger?
A: Inside the exchanger there are alternately arranged hydrogen channels and coolant channels. High-temperature coolant (60C~80C) flows through the coolant channels and transfers heat through the plates to the low-temperature hydrogen flowing through the hydrogen channels. The unique herringbone corrugated plate design creates strong turbulence and higher heat exchange efficiency.

Q6: What is the working pressure of the K series?
A: Standard type 30bar, reinforced type 45bar.

Q7: What connector types can be customized?
A: Three customizable types: quick connector, bamboo connector (silicone hose connection) and ferrule tube connector.

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.
