Research and development on a thermoelectric power generating system using low-calorie exhaust gas(Final)

The U-type Fe-Si porous thermoelectric devices (ex. /spl phi/ 30 mm /spl times/ 20 mm) were developed to recover electric power by reciprocating combustion of low calorie exhaust gas without any city gases and any pollution. The output power was finally improved to 80 mW /spl sim/ 90 mW under the critical equivalent ratio less than 0.1.
