Average current density as Boundary Condition ?

Please login with a confirmed email address before reporting spam

Hello !

I have a question. I have a model of a fuel cell.

I want to set as the boundary condition for the electronic voltage a value that represents the integration of the current density along that boundary. What I want to avoid is to set the local value of the current density and instead I want to set the total value of the current density along that boundary without specifying it locally. Is that possible ?

In my problem I am particularly interested in the information of the voltage distribution at that boundary. That is why I think that giving the exact distribution of the current as boundary condition will force my answer to behave in that specific way.

If you have a different idea of how to treat this issue I am open to suggestions.

Thanks in advance

Maria
