Summary In the present study, a numerical approach regarding the thermal management of an Mm‐based AB5‐intermetallic (MmNi4.6Al0.4) for the hydrogenation process is introduced and analysed. Several heat management scenarios are studied. The numerical model was supported and validated with experimental data in terms of hydrogenation capacity and temperature distribution. The numerical analysis is based on the introduction of the energy, mass, and momentum conservation equations to numerically describe the hydrogenation reaction. The main aim of the present study is the numerical description of the heat management when 200 g of hydrogen are stored (13 kg of the hydride). The heat management cases consider the usage of cooling tubes in combination with high thermal conductivity fins. In general, various parameters affect the efficiency of the heat management. The parameters considered are the fin thickness, the fin number—which is directly connected to the metal hydride thickness convective heat transfer coefficient. A nondimensional parameter (nondimensional conductance [NDC]) specially modified to describe the role of the fins in addition to the cooling tubes is introduced to evaluate the heat management. The target of the study was to reduce the hydrogenation time of almost 13 kg of MmNi4.6Al0.4, and from the parametric study, it has been found that the more efficient conditions are fin thickness between 5 and 8 mm and the convective heat transfer coefficient of 2000 W/m2 K.

Summary Meeting the electrical demands of remote places by integrating different renewable energy technologies into a single hybrid system is quite demanding. The integration and optimal utilization of different accessible energy resources into a self‐contained micro‐grid are examined in this article. Using the Hybrid Optimization Model for Electric Renewable (HOMER) software (Version 3.14.0), an integrated hybrid renewable energy system (IHRES) strategy has been suggested and studied. This article is mainly focused on their levelized cost of energy (LCOE) supply and annualized cost system (ACS). Two combinations of energy sources and storage technologies, that is, i) solar photovoltaic (PV)/wind/battery and ii) solar PV/wind/fuel cell (FC) for the community load have been considered for the Kutch location in Gujarat. A recently proposed novel Hybrid Chaotic Particle Swarm Optimization and Black Widow Optimization (HCPSOBWO) method is used for optimum component sizing. To validate the effectiveness of the proposed approach, the results obtained are compared with HOMER software. The findings show that the proposed algorithm has excellent convergence characteristics and the capacity to provide high‐quality output. According to the simulation findings, the suggested off‐grid‐connected hybrid solar PV/wind/FC power system is the most suitable and cost‐effective option for the given location. The suggested system will pave the way for the creation of more sustainable, effective, and robust IHRES capable of meeting the energy needs of the whole mankind.

Summary A novel hybrid 4D bio‐inspired optimization combined with an Artificial Neural Network (ANN) is proposed for finding optimal design and operational variables for a fuel cell dynamic model. In addition, a novel classification of fuel cells is proposed which can help designers and decision‐makers to set operational and contractual parameters for their desired purposes. The present article proposes three general clusters of proton exchange membrane fuel cells (PEMFCs), which help designers to choose design parameters for a vast range of applications from hydrogen vehicles to combined power generation plants. After investigating PEMFC design parameters followed by sensitivity analysis, several correlations between PEMFCs design parameters are found. For instance, the correlation between fuel cell active area and membrane thickness for optimized fuel cell units can help designers to ensure that their design is optimized. An ANN model is developed which can be used by others to ascertain in what category their fuel cell stack is.
