However, there are many problems  in the commercialization of FC from an economically and operation perspective. One of the most important problems is heat management. New heat pipes are being  developed for this purpose. A heat pipe is made from a “porous coat” on a base metal. In this study, a Cu-Ni porous layer with a thickness of ~300µm was considered as the coating on a Cu-Ni base metal with two kinds of powder (mixed and ball milled). The morphology and physical properties of the coatings, such as porosity, permeability and effective thermal conductivity, were investigated. The best permeability was obtained for the base metals coated with powder which was ball milled for 6 hours. Thermal conductivity of samples  increased (by 9.5%) when using ball milled powder. Porosity of coated samples   decreased with ball milled powder in comparison to mixed powder.
