“…More recently, Deng and co‐workers were able to oxidize the C 60 cages, to generate partially truncated fullerenes [100] . The open fullerene had a substantially higher uptake, with an outstanding H 2 capacity of 74.12 mmol g −1 reported at 120 bar and 77 K. We note that additional fullerenes have been studied for gas storage (B 40 and B 80 ), [101, 102] but these systems rely on chemisorptive processes that have significant practical barriers [22, 103] …”

Molecules with permanent porosity in the solid state have been studied for decades. Porosity in these systems is governed by intrinsic pore space, as in cages or macrocycles, and extrinsic void space, created through loose, intermolecular solid‐state packing. The development of permanently porous molecular materials, especially cages with organic or metal–organic composition, has seen increased interest over the past decade, and as such, incredibly high surface areas have been reported for these solids. Despite this, examples of these materials being explored for gas storage applications are relatively limited. This minireview outlines existing molecular systems that have been investigated for gas storage and highlights strategies that have been used to understand adsorption mechanisms in porous molecular materials.

“…[1][2][3] Because the release of hydrogen from a reversible metal hydride consumes heat, the fuel cell waste heat can be put to good use while the requirements to energy system heat management may be advantageously reduced. [4][5][6][7] The theoretical basis for understanding the reversible chemical storage of hydrogen is a thermodynamic two-phase sorbentgas equilibrium system. Such has only one degree of freedom according to the phase rule of Gibbs and either temperature or pressure may be set freely -the other quantity follows suit, thus allowing the manipulation of the reaction direction.…”

<div> <p>A simple and practical method for describing transient metal hydride tank behaviour in fuel cell energy systems is outlined, requiring only a minimum of fundamental thermodynamic and kinetic input data. The solution is developed top-down by means of the generic pressure-time course of hydrogen release from a metal hydride tank that is coupled to a fuel cell. This approach towards a comprehensive model allows for the untangling of engineering and chemistry issues and offers an alternative to the transient simulation of metal hydride bed temperature distribution. While a practitioner of the art may benefit from that result in its own right, the essence of this work rests with the paradigm of understanding the problem.</p></div>

“…The use of hydrogen as an automotive and aviation fuel requires storage systems characterised by inherent safety as well as volumetric and gravimetric efficiency. Hydrogen can be stored as compressed gas (high-pressure storage) in gas cylinders, in solid materials (metal hydrides), and in chemical form (methanol, ethanol) [1][2][3]. Compressed hydrogen storage in gaseous form in composite vessels is the method most frequently applied to supplying protonexchange membrane fuel cells (PEMFCs) used to drive electrical engines for drones.…”

The second part of the paper is aimed at the analysis of hydrogen fuel demand for the operation of a PEMFC stack. The methodology of hydrogen utilisation for the production of electrical energy and for purging (purification processes) is presented. Based on the laboratory data derived from the electrical and non-electrical parameters recorded in this part of the paper, the design of the monitoring and control system of stack performance was elaborated and the implementation of the system tested. This solution enables not only the monitoring and control of electrical parameters, temperature, and humidity, but also management of the degree of humidification of PEMFC membranes using a short-circuit unit.
