Increasing responsibility toward the environment forced the transportation sector to shift its gear toward the electric vehicle. While battery electric vehicle (BEV) have started enjoying success, it poses a question as to whether or not fuel cell vehicle (FCV) becomes redundant even before being widely deployed. The commercialization of FCV usually only comes after a long period after the prototype was introduced, signifying certain barriers to large-scale utilization. Aside from the various LCAs, studies have also tried to estimate the future cost and model FCV adoption. Due to the limited data and different regional conditions in which the project was done, these researches used vastly different scenarios and assumptions, making the result differ significantly. The lack of a clear-cut answer might indicate that the fate of FCV is not yet decided, and the PEMFC might still play a part in the green transportation era, albeit not as the dominant technology. Alternative uses and the condition required to utilize them were discussed in this short review

Hydrogen fuel cells are systems that can be successfully used to partially replace internal combustion propulsion systems. For this reason, the article presents an operational analysis of energy flow along with an analysis of individual energy transmission systems. Two generations of the Toyota Mirai vehicle were used for the tests. The operational analyses were carried out on the same route (compliant with RDE test requirements), assessing the system’s operation in three driving sections (urban, rural and motorway). Both generations of the drive system with fuel cells are quite different, which affects the obtained individual systems operation results as well as the overall energy flow. Research was carried out on the energy flow in the fuel cells, FC converter, battery and electric motor using a dedicated data acquisition system. The analyses were carried out in relation to the energy of fuel cells, battery energy and recovered braking energy. It was found that in the urban drive section of the second-generation system (due to its much larger mass), a slightly higher energy consumption value was obtained (by about 2%). However, in the remaining phases of the test, consumption was lower (the maximum difference was 18% in the rural phase). Total energy consumption in the research test was 19.64 kWh/100 km for the first-generation system compared to 18.53 kWh/100 km for the second-generation system. Taking into account the increased mass of the second-generation vehicle resulted in significantly greater benefits in the second-generation drive (up to 37% in individual drive sections and about 28% in the entire drive test).

The main objective of the paper is to determine whether latent variables (constructs) regarding tourists' motivations can be found in the studied social media use behaviour of tourists. Design/methodology/approach: The study was carried out via an on-line survey questionnaire. Responses to questions were measured on a nominal or ordinal scale. Factor analysis was used in the data analysis. The subject of the study involves the use of social media by tourists and analyses their motivation. Findings: Tourists' motivators for using social media were identified and these are: 1) Visibility in the crowd, 2) Obtaining information about nearby events, 3) Building relationships with the local community, 4) Relying on the opinions of others. Research limitations/implications:The study was carried out only in one country. There are plans to expand the study area in the future in order to make international comparisons. Moreover, motivators were not identified by age group, which is planned in future studies. Practical implications: Identification of tourists' motivation to use social media enables city managers, tourism organisations and tourism facility managers to have a targeted impact on tourist behaviour. These activities can result in the desired objectives being achieved, e.g. relations between tourists and the local community will be built. This will also enable the identification of people who are motivated to be visible in the crowd and offer them cooperation in the promotion of tourist destinations or attractions. Social implications: Identification of tourists' motivators will make it possible to influence tourists in such a way that they will participate in solving problems of the local community or provide information on situations requiring intervention in the area of tourist attractions. Originality/value: New insights on latent variables concerning tourists' motivation when using social media have been provided. The paper is addressed to city managers, tourism organisations and tourism facility managers what will help them to improve the quality of provided services.
