Noise and vibration exposure of hybrid PEM power supply users during its operation

Abstract

Proton exchange membrane (PEM) fuel cells characterized the highest available current density of electricity, but their construction uses elements, which generate noise, vibration and requires the dissipation of heat. Emitting these physical fields into the environment from this type of power sources is a disadvantage due to the low detection requirements of military installations as well as operator safety. The paper presents the study of noise and vibration exposure users of 20 Watt PEM fuel cell users.
