In order to create a finned heat sink, an array of 10 rectangular fins, with a thermal conductivity of 100 W/mK, length 7 mm, and thickness 2 mm, are distributed equally along the top and bottom to a 60 mm long square fuel cell. the tips of the fins are adiabatic. the fuel cell operates at 375K. the contact joint between has the finned heat sink and the fuel cell has a thermal resistance of Rtc''=.01 m2K/W, the base of the heat sink is 5 mm thick. what is the net power (which is equal to the overall power generated by the fuel cell minu the power dissipated through the fin array) produced by the finned fuel cell system
