摘要： Cathode exhaust of an evaporatively cooled fuel cell stack (50) is condensed in a heat exchanger (12a, 23, 23a) having extended fins (14, 25a) or tubes (24, 24a) to prevent pooling of condensate, and/or having the entire exit surface of the condenser rendered hydrophilic with wicking (32) to conduct water away. The cathode exhaust flow paths may be vertical or horizontal, they may be partly or totally rendered hydrophilic, and if so, in liquid communication with hydrophilic end surfaces of the condenser, and the condensers (49) may be tilted away from a normal orientation with respect to earth's gravity.

摘要： A fuel cell system which prevents the deterioration of the fuel cell stack when feeding of the oxidant gas is paused under a load to perform a fuel conservation operation. Controller shuts down oxidant gas compressor and cooling water circulating pump to execute fuel conservation operation at a low fuel cell system load. The controller gives a current draw instruction to electric power controller. In the fuel conservation operation, electric power controller draws a current larger than zero from fuel cell stack, and keeps the total charge drawn per unit time constant or substantially constant.

摘要： A paper guide up unit pivotally supporting a transport driven roller making contact with a transport driving roller is provided so as to be able to be displaced by the rotation of cams. The angle α made by a straight line passing the rotation axis line position of the transport driving roller and the rotation axis line position of the transport driven roller when viewed from the paper transport pathway side and a straight perpendicular to the paper transport direction is changed by the displacement of the paper guide up unit. Control means for controlling the displacement operation of the paper guide up unit reduces the angle α before the paper back end is passed through the nip point of the transport driving roller and the transport driven roller.
