Air-Cooled Fuel Cell Stack
Release time:
2025-07-04
Currently Temperature control in fuel cells is achieved through two methods: air cooling and water cooling. Water cooling is primarily used in high-power fuel cell systems, which requires additional cooling equipment and results in a more complex structure; in contrast, air cooling features a simpler structure that does not require the addition of cooling devices. The cooling system in water-cooled fuel cell stacks includes dedicated cooling channels on the bipolar plates, along with a cooling water pump, water tank, radiator, and associated piping, thereby significantly increasing system complexity. This method is generally applied in scenarios where the output power exceeds 30 kW, such as in distributed power stations and fuel cell vehicles. Air-cooled fuel cell stacks simplify the cooling, humidification, and systems such as air compressors or gas pumps by integrating the air supply and cooling systems through specially designed flow channels. This integration makes the application of fuel cells in portable power sources more convenient, primarily in situations where lower power requirements (10W-5kW) are needed, such as mobile power supplies and drones.
Air-Cooled Fuel Cell Stacks Currently, there are two types of temperature control for fuel cells: air-cooled and water-cooled. The water-cooled type is primarily used for high-power fuel cell systems and requires additional refrigeration equipment, making its structure complex. In contrast, the air-cooled type boasts a simple structure that does not require additional cooling equipment. The cooling system of the water-cooled stack features dedicated cooling channels on the bipolar plates and is equipped with a cooling water pump, water tank, radiator, and related piping, significantly increasing the system's complexity. It is typically used in scenarios where the output power exceeds 30kW, such as distributed power stations and fuel cell vehicles. The air-cooled fuel cell stack simplifies the cooling, humidification, and air compressor or pump systems by integrating the air supply and cooling systems through a specially designed flow channel structure, facilitating more convenient applications of fuel cells in portable power sources, mainly in settings with lower power requirements (10W-5kW), such as mobile power supplies and drones.
