The common method of determination of polarization and power curves of Fuel cell is to change different external resistance and read the corresponding voltage and current. I would like to ask is there another method that can do the same job without the need of changing different external resistances? May be by using the potentiostat?
Yes, a potensiostat can do that but it depends on the size of your cell.
You can simply apply a potentiodynamic sweep down from OCV but make sure your scan rate is slow enough to match steadystate outputs. Otherwise you can hold the voltage of the cell and measure the current at different fixed potentials down from OCV
