摘要： Corrosion of a metal portion such as a pipe connected to a fuel cell stack is suppressed. The fuel cell stack has a plurality of single cells which generate electrical power using an aqueous methanol solution and air and are stacked in a vertical direction. An inlet of a fuel supply manifold for distributing the aqueous methanol solution to each cell and an outlet of a fuel discharge manifold for collecting the fuel discharged from the single cells are provided in a common conductive end plate. Hence, when the discharge fuel discharged from the fuel cell stack is circulated and resupplied to the stack, the potential of the discharged fuel becomes equal to that of the liquid fuel to be supplied to the stack, whereby the corrosion of the metal portion such as a pipe, a tank, a pump, or a heat exchanger is suppressed.

摘要： Cells constituting a fuel cell stack are measured for voltages with reference to a common ground. Here, voltmeters are used to measure voltages V1 to Vn across respective series of cells which increase in number in steps of two cells. Cell voltages Vc1 to Vcn each across two cells are calculated from the voltage measurements V1 to Vn, and then a standard deviation is calculated from the cell voltages Vc1 to Vcn. The standard deviation calculated thus can be used as an index of fuel concentration since it increases largely when the fuel concentration goes out of an allowable range.

摘要： There is provided a compact and light-weight fuel cell device. The fuel cell device has a structure where a plurality of substantially horizontally-disposed cells are vertically piled to form a stack, on whose ends there are end plates and the stack is tightened with two bands. Each cell comprises an MEA comprising a pair of electrode layers and a reaction layer therebetween, and conductive separators sandwiching the MEA in which channels for flowing liquids such as a gas and a liquid fuel are formed. An unreformed organic liquid fuel is directly fed to an anode, while oxygen-containing air is fed to a cathode. In the upper part of the fuel cell device, there are an air inlet and a fuel outlet, while in the lower part of the opposite side there are an air outlet and a fuel inlet.
