**6. Conclusions**

The main task of bipolar plates in fuel cells is to ensure even distribution of reactants on electrode surface. In order to meet this requirement, solid materials are cut the channels with a variety of shapes. In the case of use of porous material, obtained by means of powder metallurgy, surface unevenness forms the channels which supply and discharge media. From the standpoint of economics, the intended porosity of material is beneficial. With consideration of seeking new solutions and opportunities in the field of material choice in order to facilitate and optimize operation of machines, it seems entirely legitimate to investigate the problems analyzed in the present study.

Based on the investigations, the following conclusions were drawn:
