We determine the thermal conductivity of single layer graphene supported on silicon nitride layer followed by a silicon substrate using a three dimensional simulation study. Temperature distribution profile along the graphene flake is obtained and heat transmission in graphene layer along with the subsequent layers is investigated by modeling the laser light as heat source. Two types of heat sources...
Proton exchange membrane is the prime part of proton exchange membrane fuel cell (PEMFC). In this work, it has focused to the proton conduction through two different conductive polymer membranes such as Nafion 212 and Fumapem AM (PBI). The conductivity has measured by the two probe method with the help of electrochemical impedance spectroscopic (EIS) analysis. To increase the conductivity, Fumapem...
