The invention provides a fuel cell impedance partition measurement device, a fuel cell and an electrical device. The fuel cell impedance zoning measurement device comprises at least two electric pile single sheets, a circuit board, a voltage acquisition circuit and a controller, the circuit board is arranged between the two electric pile single sheets, the circuit board is divided into a plurality of acquisition areas, a fixed value resistor is arranged in each acquisition area, and the voltage acquisition circuit is connected with the controller. When current flows from one galvanic pile single piece to another galvanic pile single piece, the current flows through the fixed-value resistor arranged in each area, the circuit board is electrically connected with the voltage acquisition circuit, the voltage acquisition circuit is used for acquiring voltage of each fixed-value resistor, and the voltage acquisition circuit is electrically connected with the controller. And the purpose of testing the impedance characteristic of a certain region in the single chip is achieved.
