Control strategy of a fuel-cell power module for electric forklift
Radica, Gojmir; Tolj, Ivan; Lototskyy, Mykhaylo V. (Elsevier, 2021)Fuel cell-battery hybrid systems for the powertrain, which have the advantage of emissionfree power generation and adapt to material transport and emission reduction, are investigated. Based on the characteristics of the ... -
Dehydrogenation of metal hydride reactor-phase change materials coupled with light-duty fuel cell vehicles
Nyamsi, Serge Nyallang; Tolj, Ivan; Geca, Michał Jan (MDPI, 2022)The popularity of using phase change materials (PCMs) for heat storage and recovery of metal hydrides’ reaction has grown tremendously. However, a fundamental study of the coupling of such a system with a low-temperature ... -
Fuel cell-battery hybrid powered light electric vehicle (golf cart): Influence of fuel cell on the driving performance
Tolj, Ivan; Lototskyy, Mykhaylo; Davids, Moegamat Wafeeq; Pasupathi, Sivakumar; Swart, Gerhard; Pollet, Bruno G. (Elsevier, 2013)A light electric vehicle (golf cart, 5 kW nominal motor power) was integrated with a commercial 1.2 kW PEM fuel cell system, and fuelled by compressed hydrogen (two composite cylinders, 6.8 L/300 bar each). Comparative ... -
The impact of active and passive thermal management on the energy storage efficiency of metal hydride pairs based heat storage
Nyamsi, Serge Nyallang; Tolj, Ivan (MPDI, 2021)Two-tank metal hydride pairs have gained tremendous interest in thermal energy storage systems for concentrating solar power plants or industrial waste heat recovery. Generally, the system’s performance depends on selecting ... -

Nyamsi, Serge Nyallang; Tolj, Ivan; Lototskyy, Mykhaylo (MDPI, 2019)Heat storage systems based on two-tank thermochemical heat storage are gaining momentum for their utilization in solar power plants or industrial waste heat recovery since they can e ciently store heat for future usage. ... -
Metal hydride hydrogen storage tank for fuel cell utility vehicles
Lototskyy, Mykhaylo V.; Tolj, Ivan; Klochko, Yevgeniy V. (Elsevier, 2020)The “low-temperature” intermetallic hydrides with hydrogen storage capacities below 2 wt% can provide compact H2 storage simultaneously serving as a ballast. Thus, their low weight capacity, which is usually considered as ... -
Optimal design of combined two-tank latent and metal hydrides-based thermochemical heat storage systems for high-temperature waste heat recovery
Nyamsi, Serge Nyallang; Lototskyy, Mykhaylo V.; Tolj, Ivan (Multidisciplinary Digital Publishing Institute (MDPI), 2020)The integration of thermal energy storage systems (TES) in waste-heat recovery applications shows great potential for energy efficiency improvement. In this study, a 2D mathematical model is formulated to analyze the ...
