Depth Analysis

A polymer electrolyte fuel cell (PEFC) is an electrochemical device that converts chemical energy into electrical energy and heat. The energy conversion is simple; however, the multiphysics phenomena involved in the energy conversion process must be analyzed in detail. The gas diffusion layer (GDL) provides a diffusion media for reactant gases and gives mechanical support to the fuel cell. It is a complex medium whose properties impact the fuel cell’s efficiency. Therefore, an in-depth analysis is required to improve its mechanical and physical properties. In the current study, several transport phenomena through three-dimensional digitally created GDLs have been analyzed. Once the porous microstructure is generated and the transport phenomena are mimicked, transport parameters related to the fluid flow and mass diffusion are computed. The GDLs are approximated to the carbon paper represented as a grouped package of carbon fibers. Several correlations, based on the fiber diameter, to predict their transport properties are proposed. The digitally created GDLs and the transport phenomena have been modeled using the open-source library named Open Pore Network Modeling (OpenPNM). The proposed correlations show a good fit with the obtained data with an R-square of approximately 0.98.

Energy Conversion System

In this study, a simulation model of in-grid solar-to-electrical energy conversion system is presented. In this case, the in-grid solar-to-electrical energy conversion system is small photovoltaic power plant, which was constructed by the Center for Renewable Energy and Power Quality from Faculty of Technical Sciences (FTS). Equivalent circuit diagram of photovoltaic cell is described which was used to develop the simulation model of modules. Possible types and topologies of inverters are also described. The photovoltaic power plant is described briefly, because it is necessary to understand the simulation model. The result of simulation is an electricity annual production by the power plant. These results were compared with the real values, while its get a good overlap. The paper also presents the modern modeling methods developed at Faculty of Technical Sciences in the Laboratory for RES systems.

This paper considers the theory of electron field emission from nanoscale emitters with particular focus on thermal and electrical energy transport. The foundational theory of field emission is explored, and a model is presented that accounts explicitly for the energy band curvature produced by nanoscale tip emitters. The results indicate that the inclusion of band curvature strongly influences the energetic distribution of electrons for emitter radii less than 50 nm. The energy exchange process between emitted and replacement electrons is shown to allow high local energy transfer rates that can be exploited in direct thermal-to-electrical energy conversion processes. The dependence of energy conversion rates on material and operational parameters is demonstrated. Throughout the paper, opportunities for further research involving nanoscale heat transfer, materials development, and modeling are highlighted.

Indonesia is a country known for its abundant natural potential. There are many natural resources that need attention from the government to be developed. The development of this power generator tool really requires an understanding of the design of the tools used to get optimal results. The application of tools that can be developed is through thermoelectricity which is monitored via IoT in a portable manner so that it can reach 3T areas (Disadvantaged, Frontier and Outermost). Prototypes for producing renewable and environmentally friendly energy in micro-generating systems, in which IoT-monitored portable thermoelectric generators as thermal generators can be developed to address the distribution and data of electrical energy in 3T (frontier, outermost and disadvantaged) areas based on local wisdom can be designed using 3 -D INVENTOR and simulation of materials using ANSYS and simulation of the output generated from MATLAB. Making prototypes in accordance with the concepts and designs that have been obtained previously using Microroft Visio software, INVENTOR software and evaluation of simulation results using MATLAB software. The results of the prototyping will be tested for the best temperature gradient level to produce optimal energy, so that optimal data can be obtained in simulating the micro power plant. Testing data that has been done, and used as evaluation material in the simulation that is carried out. Based on the simulation, data obtained with a minimum power of 6,215 W for 2 minutes and a maximum power of 19,932 W for 8 minutes.Keywords— Energy, IoT, Portable generator thermoelectric
