具有降噪和防振结构的泵以及使用该泵的燃料电池系统
Pump having noise-proof and vibration-proof structure and fuel cell system using the same
US-7846605-B2用于减少泵的噪声和振动
专利摘要
提供了一种具有降噪和防振结构的泵以及使用该泵的燃料电池系统。燃料电池系统包括至少一个发电机，其包括电解质膜以及附着在电解质膜两侧的阳极和阴极，通过供应到阳极和阴极的含氢燃料和氧化剂之间的电化学反应产生电能；燃料供应单元，包括用于向发电机供应氧化剂的泵；以及固定框架，设置在下框架上，泵固定到该固定框架。泵与下框架分离，并通过带形固定构件在固定框架的侧面上与固定框架固定并结合，其间插入缓冲构件。因此，可以减少泵的噪声和振动。
Original abstractThere are provided a pump of a noise suppression and vibration proof structure and a fuel cell system using the same. The fuel cell system includes at least one electricity generator including an electrolyte membrane and an anode and a cathode attached to the both surfaces of the electrolyte membrane to generate electricity energy by the electrochemical reaction between fuel containing hydrogen and oxidant supplied to the anode and the cathode, a fuel supplying unit including a pump for supplying the oxidant to the electricity generator, and a fixed frame that is provided on a lower frame and to which the pump is fixed. The pump is separated from the lower frame and is fixed to and combined with the fixed frame by the belt-shaped fixing member on the side surface of the fixing frame with a buffering member interposed. Therefore, it is possible to reduce the noise and vibration of the pump.
