“…In this context, a rationally designed BaCo 0.7 (Ce 0.8 Y 0.2 ) 0.3 O 3−δ composite could greatly increase the number of active sites, and significantly influenced the fuel cell’s operational stability [ 16 ]. A more active site of NdFeO 3 perovskite catalyst has also been reported, and exhibited favorable activity for direct methanol alkaline fuel cell (DMFC) applications [ 17 ]. Perovskite is currently one of the key electrode materials that are highly useful for the designing and development of an efficient solar-energy conversion system [ 18 ].…”

This study represents the experimental assessment of the faradaic, fuel, and energetic efficiency of active direct methanol fuel cell (DMFC). The experimental system was equipped with several sensors, HPLC and UV spectroscopy to make on-line and off-line measurements of different components. A polarization study was conducted and an experimental plan was applied to collect the process data during 3-hour runs. Finally, stoichiometric and various efficiency calculations were performed based on the system and the process data. The results showed that the cell performance was better at higher operating temperatures (70.8 mW cm −2 @75 C). Faradaic efficiency and fuel efficiency were better at low temperatures and estimated as 55.8% and 59.6% at 55 C, respectively. Energetic efficiency was better at higher temperatures due to the faster anode kinetics and was found as 12.3% at 75 C. The efficiencies were strongly dependent on methanol concentration. Methanol crossover was increased with increasing methanol concentration; hence the efficiencies were decreased.

A novel comprehensive procedure for determination of optimum operating conditions for cleaner energy production system

et al. 2018

Summary Cleaner energy production system such as direct alcohol fuel cells (DAFCs) are considered as an alternative source for generating cleaner energy. Studies based on design of catalysts, electrodes design, proton exchange membrane, and flow field were conducted for improving its performance characteristic such as power density. However, the less focus was paid on determining the operating conditions considering the uncertainties that will result in an increase of power density of DAFCs. Therefore, the present work proposes a novel comprehensive procedure involving experimental study and evolutionary approach of genetic programming (GP) in formulation of robust power density models for DAFCs. Two uncertainties such as the selection of objective function and variations in measurement of operating conditions are incorporated in framework of GP. The power density models incorporate the formulation of new objective function in GP that will result in higher accuracy of the models. Experiments performed on DAFCs validate performance of the models. Simulation profiler is then generated for models to verify its robustness in uncertain operating conditions. The inferences on relationships between power density and operating conditions for DAFCs are made by surface analysis of the models.
