“…In designing fuel cell hybrid systems, the dimensions of the DMFC stack as well as the selection of a suitable energy storage solution are important. 38 Lithium-ion batteries (LIBs) have a high power and energy density, which makes them well-suited for use in fuel cell hybrid systems. Battery systems with LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) as cathode are used for this purpose because of their high specic capacity.…”

“…Methanol fuel could be generated from natural gas and coal, as conventional sources, or from green hydrogen, captured carbon, and biomass, as non-conventional sources [101]. Methanol has a high energy density of 3800 kcal/L, which is more than that of hydrogen (658 kcal/L) at 360 atm [102,103], a low boiling temperature, a high octane number of 113 [101], low production cost [104], is cheaper than hydrogen, and easier to store and transport [105], can be used under normal temperature and pressure, does not ignite rapidly, and is biodegradable [106]. Likewise, its toxicity and corrosiveness are the main disadvantages of methanol [107,108].…”

This mini review discusses the sustainability aspects of various fuels for proton exchange membrane fuel cells (PEMFCs). PEMFCs operate by converting the chemical energy in a fuel into electrical energy. The most crucial parameters in the operation process are the temperature, pressure, relative humidity, and air stoichiometry ratio, as presented in this work. The classical structure of a PEMFC consists of a proton exchange membrane, anode electrode, cathode electrode, catalyst layers (CLs), microporous layer (MPLs), gas diffusion layers (GDLs), two bipolar plates (BPs), and gas flow channels (GFCs). The mechanical behavior and the conductivity of the protons are highly dependent on the structure of the MEAs. This review discusses the various fuels and their production paths from sustainable sources. For the fuel production process to be renewable and sustainable, a hydrogen electrolyzer could be powered from solar energy, wind energy, geothermal energy, or hydroelectric energy, to produce hydrogen, which in turn could be fed into the fuel cell. This paper also reviews biomass-based routes for sustainable fuel production.

Investigation, conservation, and exploitation of seas require platforms capable of accomplishing a wide variety of missions in harsh environments with restricted human intervention for long periods of time. Autonomous Underwater Vehicles (AUVs) are excellent tools for carrying out these missions due to their versatility and ability to access remote sites. However, despite the improvement of their capabilities, their development is not devoid of challenges. Endurance, among others, such as underwater communications or autonomy, is still a pending subject. Current battery-based solutions do not offer sufficient endurance and innovative power plants with higher energy content are needed. This work studies the advantages, in terms of endurance, of using a power plant based on Direct Methanol Fuel Cells (DMFCs) to power AUVs. In order to accomplish this, a multi-objective optimization tool that makes use of a genetic algorithm was developed. This tool allows quick preliminary design of AUVs with a DMFC-based power plant, complying with a user-defined payload, operation profile, and restrictions. Six designs based on a real AUV model were studied, and endurance values up to 2 times longer than the corresponding reference AUV were obtained. These results support the benefits of using DMFCs to power AUVs to increase their endurance.
