error in porous electrode reaction for solid oxide fuel cell?

Hello,

If you create a "porous electrode reaction" within a porous electrode, you will see this equation:
eta= Phis-Phil-Eeq


The correct voltage balance may be written as:
eta=Eeq- abs(Phis-Phil)

reference: R. Bove, S. Ubertini, "Modeling solid oxide fuel cells", Springer, 2008

anybody can explain this?

I got a negative heat source for cathode power dissipation as a result of this negative sign error!
