Ion transport rate of DFAFC, PAFC, AFC, PEMFC, DMFC and SOFC fuel cells have been studied. AFC which uses an aqueous alkaline electrolyte is suitable for temperature below 90 degree and is appropriate for higher current applications, while PEMFC is suitable for lower temperature compared to others. Thermodynamic equations have been investigated for those fuel cells in viewpoint of voltage output data. Effects of operating data including temperature (T), pressure (P), proton exchange membrane water content (λ) , and proton exchange membrane thickness ( on the optimal performance of the irreversible fuel cells have been studied. Performance of fuel cells was analyzed by simulating polarization and power curves for a fuel cell operating at various conditions with current densities.

“…The ADVISOR is an open-source software tool that is implemented in the MATLAB ® /Simulink ® environment [88]. This software tool has been frequently used in scientific studies, e.g., to simulate buses such as in References [89][90][91][92][93][94][95][96][97][98][99]. The ADVISOR's work principle is well described in References [85][86][87].…”

“…Note the energy consumption value from Curitiba (18.34 MJ/km) is based on the mean value for the real-world fuel consumption costs of 1.2987 R$/km for the bus fleet [100]. The conversion was done using the local fuel costs of 2.5621 R$/L [102] and fuel properties of 42.272 MJ/kg and 0.856 kg/L for the locally used biodiesel blend consisting of 93% petroleum diesel and 7% biodiesel [89,103].…”

Recent open-data movements give access to large datasets derived from real-world observations. This data can be utilized to enhance energy systems modeling in terms of heterogeneity, confidence, and transparency. Furthermore, it allows to shift away from the common practice of considering average values towards probability distributions. In turn, heterogeneity and randomness of the real-world can be captured that are usually found in large samples of real-world data. This paper presents a methodological framework for an empirical deterministic–stochastic modeling approach to utilize large real-world datasets in long-term energy systems modeling. A new software system—OSeMOSYS-PuLP—was developed and is available now.It adds the feature of Monte Carlo simulations to the existing open-source energy modeling system (the OSeMOSYS modeling framework). An application example is given, in which the initial application example of OSeMOSYS is used and modified to include real-world operation data from a public bus transport system.

“…An intermediate alternative between traditional and electric vehicles are hybrid and plug-in hybrid vehicles. Longer trips without recharging are possible, but emissions are not eliminated and fuel dependence continues [69,70]. In addition, other inconveniences are still present (e.g., price, insurance, reparations, double technology).…”
