Abstract

A device and method for improving stack performance of a fuel cell system are provided. The device includes a fuel cell controller that operates a stack of a normal-pressure fuel cell system. When the fuel cell controller determines that an operating state of the stack is normal and a current intake air pressure is decreased as a result of monitoring the current intake air pressure, a current output, and an exterior air temperature of the stack, the fuel cell controller increases the amount of air to be supplied into the stack by adjusting a range of a theoretical air ratio which is a theoretical ratio of an air amount to a coolant temperature in the stack.

Description

technical field [0001] The present invention relates to a device and method for improving the performance of the battery stack of a fuel cell system, and more particularly to the following device and method for improving the performance of the battery stack of the fuel cell system, which improves the performance of the battery stack under low temperature and low pressure working conditions and improve fuel efficiency. Background technique [0002] The performance of the fuel cell system stack under normal pressure operating conditions changes rapidly due to changes in the external environment (eg, external temperature, atmospheric pressure, etc.). Specifically, when the atmospheric pressure decreases, the stack performance deteriorates rapidly in proportion to the decrease in atmospheric pressure. as prior art Figure 1A to Figure 1B As shown, the pressurized fuel cell system using the compressor can overcome the degradation of the stack performance by adjusting the operati...
