Title: Fuel cell power generating device
Inventor: SASAKI YOICHI
IPC: H01M8/04
Filed: 1987-11-19
Abstract: PURPOSE:To enhance the rate of fuel utilization by introducing fuel electrode exhaust gas to a film separator device, separating into CO enriched gas and hydrogen enriched fuel gas, and mixing the hydrogen enriched fuel gas with conversion gas to accomplish a fuel gas. CONSTITUTION:Fuel electrode exhaust gas 105 generated from a fuel cell body 3 is introduced into a film separator device 7 and separated into two streams of hydrogen enriched fuel gas 106 and CO enriched gas 107 by a hydrogen/CO separating film. The hydrogen enriched fuel gas is mixed with a conversion gas 103 given by a CO transformer 2 and used in circulation as a fuel electrode supply gas 104. The hydrogen gas concentration of the hydrogen enriched fuel gas is enriched to around 40-70vol.% by selecting an appropriate hydrogen/CO separating film. Mixing this with the conversion gas drops the hydrogen concentration in the fuel gas to approx. 60-75vol.%, while there is little drop of the power generating efficiency. Thus the rise of the rate of fuel utilization due to utilization of hydrogen enrichment of the fuel electrode exhaust gas overwhelms the drop in the power generating efficiency, wherein the rate of fuel utilization amounts to approx. 90%.

Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To eliminate unnecessary switching to a city area traveling pattern at the time of traveling fast by setting the threshold value of the number of intersections within its own vehicle peripheral area for judging traveling in a city area by the attribute of a road its own vehicle is traveling on. SOLUTION: The road attribute judging means A1, F1 to H1 of a vehicle controller are connected to a navigation system provided with a gyro compass, GPS and road map information for measuring the position of its own vehicle to output the attribute of a road its own vehicle travels on to city area traveling judging means A2 to H2. The means A2 to H2 retrieves information of an area around its own vehicle from road map information of the navigation system and outputs the judging result of traveling in a city area to a vehicle control characteristic deciding means. In this case, traveling in a city area is judged when the number of intersections within an area around its own vehicle is abnormal concerning a threshold value.  Then, in the case of traveling on a national highway, etc., the threshold value of the number of intersections is increased to make it difficult to judge traveling in a city area. Thus unnecessary switching to the city area traveling pattern is prevented.
