Abstract: PURPOSE: A fuel cell is provided to use a gas diffusion layer in which a conductive polymer layer heating during operation is coated, thereby effectively preventing the condensation of moisture moving in pores of the gas diffusion layer by heating of a conductive polymer layer. CONSTITUTION: A fuel cell comprises: a membrane electrode assembly consisting of a polymer electrolyte membrane(11) and a catalyst electrode layer(12) conjugated to both sides thereof; a gas diffusion layer(13) laminated on both sides outside the membrane electrode assembly; and a separator(15) laminated on outer side of the gas diffusion layer. A conductive polymer layer(14) is formed on sites forming pores surface in the gas diffusion layer in order not to block pore. The conductive polymer layer is composed for a polymer layer to heat by formation of voltage between cathode and an anode of the catalyst layer.

Abstract: PURPOSE: A fuel cell evaluation method is provided to measure the discrete potential of each electrode of a cell without changing the structure of a measurement cell and compare the measured potential with the potential of a reference cell, thereby detecting the damage to each electrode of the measurement cell. CONSTITUTION: Hydrogen and air inlet/outlet terminals of a measurement cell and a reference cell in a normal state are connected(S1). Cell voltages of the measurement cell and the reference cell for each current density are measured(S2). Anode voltage of the measurement cell is measured by measuring voltage between anodes of the reference cell and the measurement cell for each current density(S3). Cathode voltage is calculated by subtracting the measured anode voltage from the cell voltage of the measurement cell(S4). An electrode damage degree of the measurement cell is determined by respectively comparing the cathode voltages and the anode voltages of the measurement cell and the reference cell(S5).

Abstract: PURPOSE: A method for controlling a fuel cell system is provided to efficiently increase the temperature of a stack without using a heater or reducing the amount of heater usage. CONSTITUTION: A method for controlling fuel cell system comprises: a step of calculating whether a stack temperature while being supplied to a reaction gas detected by a temperature sensor, is lower than a warm-up target operation temperature; and a step of increasing the stack temperature by increasing cooling water flux and the stack heating amount by operating a cooling pump at a maximum rotating speed, in case the stack temperature is lower than the warm-up target operation temperature.
