FLUID TRANSFER DEVICE

摘要

A fluid transfer device according to the present invention is intended to cause a fluid to travel along a channel (1). A vibrating plate (3a) for generating an acoustic wave and a reflector (2) for reflecting the acoustic wave face each other at opposite sides of the channel (1) with the channel held therebetween. The fluid is caused to travel by a sound pressure gradient formed in the channel (1) by the vibration of said vibrating plate (3a). A fuel cell according to the present invention includes a membrane electrode assembly (14) with an electrolytic membrane (14a), and an anode (14c) and a cathode (14b) arranged on opposite sides of the electrolytic membrane. The fluid transfer device according to the present invention is used to supply a fluid to the anode (14c) and/or cathode (14b) constituting the membrane electrode assembly (14).
