摘要:
An object of the present invention is to provide a production method which enables efficient production of an electro-deposited copper foil with further lower profile when compared to the low-profile electro-deposited copper foils which have been supplied to the market and is excellent in mechanical strength. For the purpose of achieving the object, a production method adopted obtains the electro-deposited copper foil by electrolyzing a sulfuric acid based copper electrolytic solution which contains a quaternary ammonium salt polymer having cyclic structure and chlorine, wherein for the quaternary ammonium salt polymer contained in the sulfuric acid based copper electrolytic solution, a DDAC dimer or higher polymer is used. For the quaternary ammonium salt polymer, a diallyl dimethyl ammonium chloride polymer having a number average molecular weight of 300 to 10000 is preferably used. The sulfuric acid based copper electrolytic solution preferably contains bis(3-sulfopropyl) disulfide or 3-mercapto-1-propanesulfonic acid that is a compound having a mercapto group.

To provide a fuel cell system capable of performing a purge operation necessary for realizing a stable output and being miniaturized without using a controller or a sensor, there is provided a fuel cell system having a main power generation part and a sub-power generation part positioned on a downstream side of a fuel flow path of the main power generation part, including: a purge valve provided on a downstream side of the fuel flow path of the sub-power generation part; and an actuator for opening/closing the purge valve with an electromotive force of the sub-power generation part.
摘要:
A fuel cell stack is divided into a main power generation portion and a sub power generation portion. A variable load large in variation of output current is connected to the main power generation portion located upstream in a fuel flow and a steady load small in variation of output current is connected to the sub power generation portion located downstream in the fuel flow. This causes a fuel cell unit constituting the sub power generation portion to continue consuming a constant fuel by constant power generation and also causes hydrogen gas to continue flowing at a constant flow rate into the fuel cell unit, thereby preventing impurity gas concentrated and stored in the fuel cell unit from diffusing toward the upstream.

There is provided a fuel cell system including a fuel supply control mechanism which is disposed between the fuel tank and the fuel cell and capable of interrupting the supply of the fuel; and a temperature sensor provided to a circuit connecting the fuel supply control mechanism to the fuel cell, for changing a resistance value according to at least one of a temperature of the power generation of the fuel cell and a temperature of an electronic device supplied with electric power from the fuel cell, in which the fuel supply control mechanism is operated by a change in the resistance value of the temperature sensor so that the supply of the fuel is interrupted. The system enables more reliably interrupting a supply of a fuel by a passive structure in a control when a temperature of a power generation portion of a fuel cell exceeds an allowable range.
