摘要： A fuel cell device has a small and compact structure as a whole. The fuel cell device employs a fuel cell (e.g., direct methanol fuel cell of an MEA structure) using liquid fuel. Diluted liquid fuel is prepared by diluting the liquid fuel (methanol-contained liquid in the case of DMFC) with dilution liquid, and is supplied to the fuel cell. A first pump unit stacked on the fuel cell supplies the diluted liquid fuel to the fuel cell while diluting the liquid fuel by mixing the liquid fuel and the dilution liquid together. A second pump unit stacked on the fuel cell collects liquid (water usable as dilution liquid in DMFC) produced by an electrochemical reaction in the fuel cell.

摘要： A method and a device are provided which can mix two liquids faster at a precise mixing ratio. The method for mixing at least two liquids transported in respective channels includes transporting, of the two liquids, a liquid having a low mixing rate intermittently in one of the channels, and transporting, of the two liquids, a liquid having a high mixing rate so as to join the liquid having a low mixing rate from both sides of the channel for the liquid having a low mixing rate.

摘要： The micro pump 100 comprises a first flow pass 115 for changing the flow pass resistance in accordance with the differential pressure, a second flow pass 117 wherein the percentage change in flow pass resistance relative to the differential pressure is less than that of the first flow pass 115, pressure chamber 109 connected to the first flow pass 115 and the second flow pass 117, and a piezoelectric element 107 for changing the pressure within the pressure chamber 109 so as to transport minute amounts of fluid with high precision using a simple construction. The ratio of the flow pass resistance of the first flow pass 115 and the flow pass resistance of the second flow pass 117 differs by changing the pressure within the pressure chamber 109 via the piezoelectric element 107, such that fluid can be transported in a standard direction and an opposite direction.
