FUEL CELL SYSTEM AND METHOD OF CONTROLLING FUEL CELL SYSTEM

A control unit of a fuel cell system acquires a service operating point, repeats a process of calculating a distance between the service operating point and a surging region, while transferring an operating point of a turbo compressor from a first operating point to a second operating point outside...

description A control unit of a fuel cell system acquires a service operating point, repeats a process of calculating a distance between the service operating point and a surging region, while transferring an operating point of a turbo compressor from a first operating point to a second operating point outside the surging region, sets opening degrees of a pressure adjusting valve and a bypass valve such that the turbo compressor operates at a required operating point, when the distance exceeds a threshold, and corrects at least one of the opening degrees of the pressure adjusting valve and the bypass valve such that the at least one of the opening degrees becomes larger than an opening degree set such that the turbo compressor operates at the required operating point, when the distance is equal to or shorter than the threshold.
