Abstract
Description
Technical Field
[0001] The utility model belongs to the field of fuel cell intercoolers, and in particular relates to an insulating vibration damping pad for a fuel cell intercooler. Background Art
[0002] Fuel cell systems require an intercooler. When air is compressed by the air compressor, its pressure and temperature rise significantly, reaching as high as 150°C. However, the ideal operating temperature of a proton exchange membrane fuel cell is approximately 80°C. Without proper cooling, high-temperature air entering the fuel cell stack will negatively impact its performance and may even damage the proton exchange membrane. Therefore, to ensure the fuel cell stack's intake air temperature remains within an appropriate range, an intercooler is installed after the air compressor to reduce the air temperature.
[0003] The current intercooler lacks a mounting bracket with insulation and shock absorption functions during use. Utility Model Content
