I'm modeling a membrane humidifier for PEM fuel cell, with fluent.
In this problem air flow pass over the membrane. membrane absorb air humidity.
I've activated fuel cell module in fluent and membrane has selected as electrolyte zone. The membrane water transport is activated in PEM module.

after initializing i face this error:


Error at Node 0:


Cell voltage value of -2000000.000000 unphysical.

Please Help Me!!

Thank u

Maybe the boundary condition of "Electic potential"or "protonic potential"is not rightly given

i have check but this is not mistake

There are problems of potential boundary conditions. Under the Condition of constant voltage Boundary, the Electric Potential of the end face of the anode collector should be set as Specified Value with the value of 0. The corresponding boundary of the cathode collector surface is also Specified Value with the value of specified voltage .
