I am modelling a low temperature PEM fuel cell model using the application library of HT-PEM fuel cell. I need to model electro-osmotic flow in the membrane. For this I need pressure value at the boundary of membrane as shown in the figure marked in blue and red.
The initial conditions of pressure are given at inlet and outlet of gas channels. But for giving boundary condition for membrane, how do i get the values of pressure ?

i tried giving comp1.pa in the input of boundary condition for input pressure at the membrane and comp1.pc as output pressure boundary condition for membrane. But i am getting error in the solver.
