<P>PROBLEM TO BE SOLVED: To provide a fuel cell device in which power generation efficiency can be improved even though a decrease in thickness is achieved, and also provide a gas jet blowing device and its power generation method capable of being used for a fuel cell device. <P>SOLUTION: The fuel cell device 1 includes a main body 201 to have flow passages R1, R2 and a cell 220 in order to generate electromotive force by using a gas to circulate in the flow passages R1, R2, and a gas jet blowing device 101 which is arranged in the neighborhood of the main body 201 and which blows the air as a pulsating current and blows it into the flow passage R1. Because of this, the air can be supplied to the cell 220 so that the air is blown into the flow passage R1 as the pulsating current by the gas ejection device 101. If a vibration plate is used as a means to make the gas be blown out from the gas jet blowing device 101, while the decrease in the thickness is achieved, a boundary layer of the air which has been apt to be formed at the flow passage R1 conventionally, or its staying air can be agitated, thereby the power generation efficiency can be improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
