An air intake system must satisfy three main functions: air filtration, air delivery to the engine, and the minimisation of orifice noise emission. At the same time, however, the intake system must comply with the packaging constraints in the engine compartment. The same applies to the exhaust system, with the exception of the filtration function. By determining the noise emission of the source compressor through computer simulation, the intake and exhaust system could be optimised. The result was a noise reduction of 25 dB[A]. This is sufficient for a passenger car application. As opposed to the intake system, however, the exhaust system has the problem of a high accumulation of water requiring a drain system. Due to cold combustion, plastic is an ideal material for the mass production of air and exhaust systems in fuel cell engines for passenger car applications.
