The operating parameters of the active direct methanol fuel cell (DMFC) are essential factors that affect performance. However, it is challenging to maintain optimal maximum output power density due system’s complexity, conditions variation, and correlations between those parameters. This paper proposes an adaptive joint optimization method for methods include numerical simulation operation Bas...

This work describes for the first time a paper-based direct methanol fuel cell platform (PB-DMFC) that functions as an energy source and biosensor, assembled on simple paper substrate point-of-care (POC) applications, targeting sarcosine proof-of-concept. Specifically, strip was developed from square of Whatman paper, acting substrate. The treated with impermeable agent (paraffin solution) supp...

The electrochemical reduction of CO2 is an efficient method to convert waste into hydrocarbon fuels, among which methanol the direct liquid fuel in cells (DMFC). Copper most widely used catalyst for reaction (CO2RR); affected by surface morphology copper. Here, effect and mechanism CO2RR on three typical low-index Cu (100), (110) (111) surfaces are studied. According our results, provides optim...

This paper reviews the chemical and electrochemical depositions of platinum group metals (PGMs) from aqueous solutions. With a brief introduction on the fundamental aspects of chemical/electrochemical depositions, the review describes recent advances in chemical and Abbreviations: CD, cathode current density expressed as amperes per cm2; CE, cathode current efficiency; dc, direct current; DMFC,...

In order to determine the working conditions for direct methanol fuel cell and to gain higher performances, two one-dimensional, steady-state numerical models have been presented to evaluate the performance of direct methanol fuel cells (DMFCs) using Matlab. Genetic algorithm and direct Monte Carlo algorithm have been employed to determine the optimization operation conditions of the DMFC. The ...
