Test bench for fuel cell system air supply modules
Development and service life study of compressors for the air supply in fuel cell systems. The compressor is attached to the test bench and draws in air from the test room environment via an intake silencer. This air is compressed, humidified and released again in an expander. Air conditioning is an available option.
