摘要： A method of measuring methanol vapor concentration on a real-time basis and a methanol vapor concentration measuring apparatus used in fuel cells. The method of measuring methanol vapor concentration involves using an absorption spectrometry technique, that is, after measuring intensities I0 and I1 of light of a laser before and after passing through a space filled with methanol vapor and into which light is irradiated, the methanol vapor concentration is calculated by substituting the intensities I0 and I1 into an equation defined as I1/I0=exp (K·L·C), where K represents the absorption coefficient, L represents the length of the space through which the laser passes, and C represents the methanol vapor concentration.

摘要： A direct liquid feed fuel cell system that includes a housing, a fuel cell stack in which air flow channels are formed, in the housing; and a fan that supplies air between the housing and a part of the air flow channels, wherein the fuel cell stack is obliquely mounted toward the fan. The fuel cell system can be arranged so that the airflow channels are substantially vertical, in order for air to be supplied between the housing and an upper part of the airflow channels, with the fuel cell stack downwardly obliquely mounted toward the fan. Furthermore, an outlet in the housing on an opposite side of the fuel cell stack from the fan can allow air that has passed through the air flow channels to be exhausted from the fuel cell system after passing through a space between a part of the fuel cell stack and the housing.

摘要： A mobile communication terminal includes an upper body, a lower body and a swivel hinge unit connecting the upper body and the lower body such that the lower body swivels about the upper body. Before the swiveling movement, the upper and lower bodies form a horizontal axis, and the swivel hinge unit has a central axis arranged with an inclined angle with respect to the horizontal axis. After the swiveling movement, the upper and lower bodies are arranged relative to each other to form an obtuse tilting angle. The inclined angle of the swivel hinge unit is ½ of the tilting angle, and the tilting angle can be 5° to 30°. The upper body includes a display, and the lower body includes a key input unit.
