Disparity in Anode and Cathode Current Density

Dear all,
I am running a two-phase PEMFC model in Fluent. According to reports, I have to use I_anode for my IV curve. In my initial simulation, I_A and I_C were the same. To match up with the experimental data, I changed some values and I noticed a huge disparity between I_A and I_C. I have like 1.3A/cm2 at the anode and 0.32 at the cathode. Is this normal? what can I do?
