Classification: CPC H  Y | IPC H

Claim 0:
1. An apparatus for sensing voltage information of a fuel cell, the apparatus comprising:
a sensing unit configured to sense voltages of each cell of a plurality of cells included in a fuel cell;
a controller configured to control the sensing unit to sense the voltages of each cell of the plurality of cells after a command of an upper controller, or to transmit information of the sensed voltages of each cell of the plurality of cells to the upper controller; and
the upper controller configured to:
detect an error cell by calculating output power of the fuel cell based on the information of the sensed voltages received from the controller,
stop operation of the error cell to prevent damage to a surrounding cell, among the plurality of cells, and
control the output power in real time in correspondence with a state of the fuel cell.
