Fig 10. Experimental results:(a) Power generated in he case of uniform and nonuniform temperature distribution versus the temperature change between the hot and cold surfaces of the thermoelectric module,(b)electric current generated in the case of uniform and non-uniform temperature distribution versus the temperature change between the hot and coid surfaces of the thermoelectric mpdule, and(c) voltage output in the case of uniform and nomtemperature distribution versus the temperature change between the hot and cold surfaces of the thremoelectric module.
