In this article we study the existence of non-constant stable stationary solutions to the the diffusion equation on a surface of revolution whose border is supplied with zero Neumann boundary condition. Sufficient conditions on the geometry of the surface and on the diffusivity function a are given for the existence of a function f such the problem possesses such solutions.
