1. An apparatus for sensing voltage information of a fuel cell, the apparatus comprising:
a plurality of sensing units each configured to: measure voltage values of a plurality of measurement cells included in a fuel cell stack and detect a diagnosis value for diagnosing the fuel cell stack based on the measured voltage values; and
a controller configured to receive the diagnosis values from the plurality of sensing units and transmit the diagnosis values to an upper controller,
wherein each sensing unit of the plurality of sensing units is configured to: detect the diagnosis values for respective measurement cells of the plurality of measurement cells and transmit the diagnosis values to at least one sensing unit of the plurality of sensing units or to the controller, which is a transmission target of the diagnosis values, based on a connection relation between sensing units of the plurality of sensing units, and
wherein when the diagnosis values are received from another sensing unit among the sensing units, each of the sensing units is configured to finally detect a diagnosis value, which is to be transmitted to the transmission target, using the diagnosis values measured by each of the sensing units and the diagnosis values received from the another sensing unit, and to transmit the finally detected diagnosis value to the transmission target.
 
3. An apparatus for sensing voltage information of a fuel cell, the apparatus comprising:
a detection section configured to detect diagnosis values of measurement cells included in a fuel cell stack based on voltage values of the measurement cells;
a storage section configured to store the diagnosis values detected by the detection section; and
a control section configured to:
generate diagnosis values, which are to be transmitted to a transmission target, using the diagnosis values stored in the storage section and diagnosis values received from a sensing unit, and
transmit the generated diagnosis values to the transmission target,
wherein the control section is configured to detect diagnosis values for the respective measurement cells and transmit the diagnosis values to the sensing unit or the controller, which is the transmission target, based on a connection relation therebetween, and
wherein when the diagnosis values are received from another sensing unit, the control section is configured to: generate diagnosis values, which are to be transmitted to the transmission target, using the diagnosis values measured by the control section and the diagnosis values received from the another sensing unit, and to transmit the generated diagnosis values to the transmission target.
