Considering the prevailing energy crisis and fast economic growth, the demand for clean alternative power sources for applications in stationary, transportation, and the portable sectors is increasing continuously. In this regard, fuel cell (FC) technology has already proved its potency as an alternative power unit for stationary applications, and now it is gearing up to serve in portable and transportation sectors. This literature review demonstrates the current status, technical accomplishments, and future perspectives of the hydrogen FC in both transportation and portable sectors. It highlights the advancement and current status of FC technology in the urban transit system admitting all the major field applications such as land ways, waterways, airways, and railways. It also highlights small power units for military equipment, auxiliary power units (APU), educational kits, and consumer electronics gadgets such as laptops, smartphone, and chargers, etc. Moreover, the major obstacles that restrict the widespread commercialization of FCs such as fuel storage and distribution, proper hydrogen infrastructure, and operational costs are thoroughly discussed. The future perspective and target toward the development of cost-effective stack are also reported here. We believe that it could serve as a valuable resource for the researchers working on the development of FC technology.

Autonomous Underwater Vehicles (AUVs) are vehicles that are primarily used to accomplish oceanographic research data collection and auxiliary offshore tasks. At the present time, they are usually powered by lithium-ion secondary batteries, which have insufficient specific energies. In order for this technology to achieve a mature state, increased endurance is required. Fuel cell power systems have been identified as an effective means to achieve this endurance but no implementation in a commercial device has yet been realized. This paper summarizes the current state of development of the technology in this field of research. First, the most adequate type of fuel cell for this application is discussed. The prototypes and design concepts of AUVs powered by fuel cells which have been developed in the last few years are described. Possible commercial and experimental fuel cell stack options are analyzed, examining solutions adopted in the analogous aerial vehicle applications, as well as the underwater ones, to see if integration in an AUV is feasible. Current solutions in oxygen and hydrogen storage systems are overviewed and energy density is objectively compared between battery power systems and fuel cell power systems for AUVs. A couple of system configuration solutions are described including the necessary lithium-ion battery hybrid system. Finally, some closing remarks on the future of this technology are given.

“…Nowadays, there are constructions of submarines and unmanned underwater vehicles using PEM stacks to generate an electric energy needed for their working. The most mature examples of underwater platform with PEM fuel cells are German submarine class 214 [4] and Japan AUV (Autonomous Underwater Vehicle) Urashima [16]. Another interesting examples of using fuel cell in marine application are AUV Hugin [5] with alkaline aluminium hydrogen peroxide semi fuel cell and AUV Clipper [6] using magnesium fuel and oxygen from the sea.…”
