Driver circuit

Disclosed is a driver circuit for producing a voltage output in highly precise fashion with little consumption of power. The driver circuit includes a first follower transistor and a first switch connected between an output terminal and a high-potential power supply; a first current source and a second switch connected serially between the output terminal and a low-potential power supply; a second follower transistor and a third switch connected between the output terminal and the low-potential power supply; a second current source and a fourth switch connected between the output terminal and the high-potential power supply; and first and second gate bias control means for supplying the first and second transistor with bias voltages based upon an input signal voltage. At one timing in a low-potential data output interval, the first switch is turned on, thereby causing the first transistor to perform a follower operation to drive output voltage to the vicinity of a certain voltage defined in conformity with the input signal voltage. The second switch is turned on at a timing subsequent to the one timing, thereby controlling the drain current of the first transistor and driving the output voltage to the certain voltage highly precisely in conformity with the input signal voltage. At one timing in a high-potential data output interval, the third switch is turned on and then the fourth switch is turned on subsequently.

Film electrode composite element and production method therefor, and fuel cell

It is an object of the present invention to provide a method of producing a membrane electrode assembly using an interface resistance reducing composition which can simply reduce the resistance of the interface between an electrode and an electrolyte membrane in a short time at low temperatures at low pressure without polimerization while maintaining an effect of suppressing a fuel crossover even with an electrolyte membrane having high heat resistance, high strength, a high tensile elastic modulus and a low water content. This is achieved by a method of producing a membrane electrode assembly formed by sandwiching an electrolyte membrane between a pair of electrodes, comprising the steps of bonding at least one electrode to the electrolyte membrane sandwiching an interface resistance reducing composition containing a plasticizer between the electrode and the electrolyte membrane, and a membrane electrode assembly formed by sandwiching an electrolyte membrane between a pair of electrodes, wherein the membrane electrode assembly has a layer (A) at least between one electrode and the electrolyte membrane, and the value of the storage modulus C is 1 GPA or more when the storage moduli of the electrolyte membrane and the layer (A), which are measured with an ultramicro penetrometer, are regarded as C and D, respectively.
