Fuel-cell device, gas-injecting unit, and method for generating power using the fuel-cell device

Abstract

A fuel-cell device according to the present invention includes a fuel-cell unit having a first and second flow channels and a cell for generating an electromotive force with the use of gases circulating in the first and second flow channels, and a gas-injecting unit disposed adjacent to the fuel-cell unit and injecting air into the first flow channel in the form of a pulsating flow. With this structure, the gas-injecting unit injects air into the first flow channel in the form of a pulsating flow to supply the air to the cell. When a vibrating plate is used as means for injecting the gas from the gas-injecting unit, the fuel-cell device can be low-profiled. In addition, boundary layers of air that are easily formed in the first flow channel or the retained air can be agitated to improve the power generation efficiency.
