half elements on boundary path / boundary node add to unknowns

I have a problem with convective boundary conditions.
I am using two steps now. First step is an explicit method for determining boundary face value. Second step is solving internal cell values by implicit method with fixedValue on boundary. This way works, but it is sometimes so difficult, stability problems and so on...
I need use full implicit method (boundary face value will be obtained from matrix, too).
Does exist any way, half element on boundary (cellpoint is equal to boundary face point) or add boundary points to matrix (unknowns)...?
