“…Also historical aspects in fuel-cell technology have been conversed [10]. Various methods for generation of energy for portable devices including fuel cell technology as a practical solution and hybrid of various technologies including like piezoelectric, photo voltaic are studied [11]. Hence a comprehensive approach in the modeling of fuel cells is necessitated.…”

Abstract-We have proposed a unified approach to the modeling and study of developments in the field of Nanotechnology and its application in futuristic Nano-enabled Cells. The necessity of a nonporous membrane has been eminent in recent fuel cells. The need for MEMS based models for porous silicon based membranes based on nano imprints technology has been met by modeling it in SUGAR in MATLAB environment. We have identified and categorized the domains of Nano enabled solar cells and have put forth a proposition for multi scale modeling of Solar cells. Multi scale modeling on HPC (High performance computing) of a Nano enabled solar cell is shown under MCCS (Microsoft compute cluster environment) environment using extreme optimization numerical library is implemented. Distribution and performance analysis of four levels of computation in a multi scale model is implemented with the distribution being carried out from classical semi-conductor to quantum levels as to accurately predict the behavior and properties of the solar cell as per the needs of the engineering of devices.

“…Thus, the lithium batteries that are currently employed will become insufficient to power these mobile devices in the future. Direct methanol fuel cells (DMFCs), for which the theoretical energy density is 10 or more times greater than that of current lithium cells, are expected to become the future power sources for mobile devices [1,2] .…”

The power consumption of portable devices such as smartphones and notebook PCs has increased in recent years. Therefore, these devices require a high energy density power supply. Direct methanol fuel cells (DMFCs), for which the theoretical energy density is 10 or more times greater than that of current lithium ion batteries, are expected to be the future power sources for such devices. We have previously proposed a zigzag-type DMFC that is suitable for mass production, because it does not require complicated separators, unlike the conventional stack-type DMFC. We propose an air-supply method that has an air-flow path based on semi-active air supply conditions.

“…It is also expected that for high performance, the energy consumption of such mobile devices will increase. Direct methanol fuel cells (DMFCs) are considered to be capable of meeting these energy requirements because they have a higher energy density than the lithium ion batteries presently used for portable devices [1,2]. Since the output of a DMFC is only approximately 0.5 V, multiple DMFCs must be connected in series to construct a single operational cell.…”

The power consumption of portable devices such as smartphones and notebook PCs has been increasing in recent years as the performance of these devices has advanced. Consequently, a power supply with a higher energy density is required. Direct methanol fuel cells (DMFCs) have a theoretical energy density that is ten or more times greater than that of the current lithium ion batteries, which makes them candidate power sources for such devices. However, the configuration of a plurality of cells in current DMFCs is too complex. To simplify the manufacturing process for DMFCs, we have previously proposed a zigzag-type structure. This type of structure can be problematic with regard to maintaining an adequate supply of air and methanol. In the present study, the effect of an active supply method for either reactant on the DFMC characteristics is investigated.
