摘要： A fuel cell system includes a fuel cell, a fluid passage for warming, a gas-liquid separator, a supply passage and a recirculating module. The fuel cell generates power with supply of a reaction gas. The gas-liquid separator separates moisture contained in an anode exhaust gas which is discharged from the fuel cell. The supply passage returns the anode exhaust gas, from which the moisture has been separated by the gas-liquid separator, to an inlet side of the reaction gas. The recirculating module mixes the anode exhaust gas, which is returned via the supply passage, with the reaction gas. The gas-liquid separator lies adjacent to the recirculating module, and the fluid passage for warming is disposed between the gas-liquid separator and the recirculating module.

摘要： Provided is a method for canceling background noise of a sound source other than a target direction sound source in order to realize highly accurate speech recognition, and a system using the same. In terms of directional characteristics of a microphone array, due to a capability of approximating a power distribution of each angle of each of possible various sound source directions by use of a sum of coefficient multiples of a base form angle power distribution of a target sound source measured beforehand by base form angle by using a base form sound, and power distribution of a non-directional background sound by base form, only a component of the target sound source direction is extracted at a noise suppression part. In addition, when the target sound source direction is unknown, at a sound source localization part, a distribution for minimizing the approximate residual is selected from base form angle power distributions of various sound source directions to assume a target sound source direction. Further, maximum likelihood estimation is executed by using voice data of the component of the sound source direction passed through these processes, and a voice model obtained by predetermined modeling of the voice data, and speech recognition is carried out based on an obtained assumption value.
