Abstract

Purpose of this paper is to evaluate phosphoric
acid fuel cell (PAFC) - thermoelectric generator hybrid system with economic
and thermoeconomic point of view. Firstly, basic equations of PAFC,
thermoelectric generator and hybrid system are described. Secondly, basic
performance parameters like power output, energy efficiency, exergy efficiency
and exergy destruction rates are investigated. Finally, cost equations are set
up to determine economic results of the considered system, in addition to that,
these system are considered by using EXCEM analysis. According to results, the
maximum total cost of the hybrid system is obtained j= 10900 am^-2, exergy loss ratio to capital cost (ec) of the hybrid system increases
dramatically after the point where is  j= 11000 am^-2. Maximum power
density, maximum energy efficiency and of the hybrid system are 8735.340 wm^-2,
81.35% and 86.6% respectively.
