How To Read Values From Polarisation Curve


V1 : Voltage when 1Amps of current flows through the fuel cell to the load.

Vnom,Inom : This is essentially obtained the intersection point of Polarisation curve and the Power curve of the fuel cell.

Vmin,Imax : This point indicates the maximum current that the fuel cell can produce and the corresponding voltage when that current is being drawn from the fuel cell.

Eoc : This is obtained when the Polarisation curve intersects the Voltage axis.

polarisation curve

Enter the input parameters in the form below :


Quantity Value Units
Ideal gas constant (R) : J/(mol K)
Faraday's constant (F) : As/mol
Number of moving electrons (z) : ---
Temperature (T) : K
Number of cells : ---

Enter the following values from the polarisation curve :


Quantity Value Units
