摘要： A fuel cell stack has plural fuel cells stacked in series along a direction vertical to a main surface of each fuel cell. Each fuel cell has a lamination body made of an anode, a cathode, and a polymer proton exchange membrane. The lamination body is sandwiched between a pair of separators. Each of the anode and cathode has a catalyst layer and a diffusion layer laminated. A water collecting groove and fuel gas passages are formed in the inner surface of each separator. The bottom end of the water collection groove is lower in position than the end of the catalyst layer and the diffusion layer. The water collecting groove is not joined to the fuel gas passages and collects water produced by electrochemical reaction in each fuel cell, and drains the collected water.

摘要： This fuel cell system is for suppressing a backflow of water from an exhaust pipe outlet that discharges a reactant-off gas, without decreasing the performance and fuel consumption of a fuel cell, the exhaust pipe being configured to switch between a main discharge pipe and a sub discharge pipe by a switching means to discharge the reactant-off gas. The sub discharge pipe includes a rising gradient portion formed to incline upwards above a gradient of the main discharge pipe and a falling gradient portion formed to incline downwards at the downstream of the rising gradient portion. The switching valve switches to allow the reactant-off gas to be discharged from the main discharge pipe if an amount of reactant-off gas to be discharged is equal to or above a threshold value of an amount of discharge, and allow the reactant-off gas to be discharged from the sub discharge pipe if the amount of reactant-off gas to be discharged is below the threshold value of the amount of discharge.

摘要： A fuel cell system includes a fuel cell, an operation controller and an air-conditioning mechanism. In response to a heating request for the air-conditioning mechanism during ordinary operation where the fuel cell is operated at an operating point on a current-voltage characteristic curve of the fuel cell, the operation controller compares a heat value-based required current value with an output-based required current value. When the output-based required current value is equal to or greater than the heat value-based required current value, the operation controller causes the fuel cell to be operated at an operating point on the current-voltage characteristic curve. When the output-based required current value is smaller than the heat value-based required current value, the operation controller controls the operating point of the fuel cell to an operating point of lower power generation efficiency than that of the operating point on the current-voltage characteristic curve.
