Abstract  We consider the problem of finding pairs (\lambda; u), with \lambda > 0 and u a harmonic function in a three dimensional toruslike domain D, satisfying the nonlinear boundary condition \partial_n u = sinh u on \partial D. This type of boundary condition arises in corrosion modelling (Butler Volmer condition). We prove existence of solutions
which concentrate along some geodesics of the boundary as the parameter \lambda goes to zero.
