Title: Fuel cell system
Inventor: YASUO KOJI
IPC: H01M8/24
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent channels from being blocked by condensed water while preventing a voltage drop to the utmost. SOLUTION: As shown in Figure (a), both fans F1, F2 are driven so as to generate an air flow from the right to the left, thus sending air into all cells from the right to the left. Humidity and temperature increase with time within air channels. Cell voltage beings to drop as the humidity and temperature become uneven. The drop of cell voltage is periodically detected with respect to a fixed number of cells. If the detected value of any cell is lower than a set value, the drive of the fan F1 is changed to generate an air flow from the left to the right, as shown in Figure (b). Further, based on the detected value of cell voltage, the drive of the fan F2 is changed to generate an air flow from the left to the right, as shown in Figure (c).  Repetition of above operation to change the air-flow direction based on detected cell voltage enables the humidity and temperature in the fuel cells to be uniformed, and thus phenomena such as channel blocking by water can be beforehand prevented.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To solve points of problem in that a base stock for a member to be treated is confined with the roughened surface forming method by the conventional etching and sandblasting, and simultaneously, a uniform roughened surface is not obtd. and as much improvement of performance as expected is not obtd. when more water-repellent property is improved by roughening the surface of the member to be treated. SOLUTION: The forming method for the water-repellent surface 1 is to form a particle film 3 on the surface 2a of the member 2 to be treated by executing the vacuum-deposition of tin under the state where the temp. of this member 2 to be treated is set at <=100 deg.C prior to the formation of the water- repellent coating film, and thereafter, the formation of the water-repellent coating film 4 is executed. Consequently, fine and uniform roughened surface is easily formed on the surface of the member 2 to be treated, thereby remarkably improving the water-repellent property, and simultaneously, forming the particle film 3 at low temp. and not selecting the base stock for the member 2 to be treated.
