Abstract
A fuel cell system for modulating an offset of a hydrogen pressure sensor is provided. The fuel cell system includes a stack with a plurality of cells and each cells includes a first electrode to which hydrogen is supplied, a second electrode to which oxygen is supplied, and a membrane electrode assembly arranged between the first and second electrodes to produce electricity by reaction between the hydrogen and the oxygen. The hydrogen pressure sensor is connected to each cell to sense a pressure of the hydrogen supplied to the first electrode. A controller that which of the cells is supplied with insufficient pressure of hydrogen and modulates the offset of the hydrogen pressure sensor connected to the cell to which the hydrogen is supplied with insufficient pressure, to then supply the hydrogen to the first electrode at an appropriate pressure.
