Thermal and structural analysis is one of the basic elements desired to guarantee great performance polymer electrolyte membrane fuel cell (PEMFC) stacks and plays a necessary part in fuel cell stack performance ,comprehensive system efficiency and durability .The choice of the great performance stack upon on the particular application, weight, size, complexity, cost and design. This study presents a three-dimensional model includes the structural and the thermal analysis into a novel Model bipolar plate in (PEMFC).The Analysis was performed to evaluate the temperature distribution and structural deviation as well as displacement values in three dimensional models. Also, this advance model combines the effect of stresses due to temperature gradient and external load. The modeled field was forming from three various domains and there are various material models current for both titanium and aluminum. The results showed that maximum temperature occurs at the second domain and decrease gradually as we head toward the surrounding of the plate and it is a minimum at outer surfaces. On the other hand the thermal loads create stresses that are one order quantity of magnitude bigger than those produced by the exterior pressure loads. The maximum stresses gradient occur at the buffer region between the first domain and the third domain and the stresses is almost uniformly distribution at the second domain and some part of the first domain. Furthermore, the loads are far from the dangerous values; however the displacements can be significantly more critical.
