“…Suitable monolithic and microstructured reactors are known for their excellent mass and heat transfer behavior, and thus they have been increasingly explored as a reactor configuration in the reforming stage. Ideally they would be built as cross-or counter-flow heat exchanger in which the endothermic reforming reaction would proceed in one channel system and an exothermic reaction in the other, [131][132][133] for instance the catalytic combustion of the anode off-gas, which needs to be carried out anyway. As attractive as such options appear, they have not yet made it beyond the laboratory scale, possibly owing to the limitations posed upon the system by the need to match both reactions ideally to each other at different temperature and load conditions.…”

Hydrogen is a promising energy carrier in future energy systems. However, storage of hydrogen is a substantial challenge, especially for applications in vehicles with fuel cells that use proton-exchange membranes (PEMs). Different methods for hydrogen storage are discussed, including high-pressure and cryogenic-liquid storage, adsorptive storage on high-surface-area adsorbents, chemical storage in metal hydrides and complex hydrides, and storage in boranes. For the latter chemical solutions, reversible options and hydrolytic release of hydrogen with off-board regeneration are both possible. Reforming of liquid hydrogen-containing compounds is also a possible means of hydrogen generation. The advantages and disadvantages of the different systems are compared.

“…Indeed, metal foams have been used to produce filters (Koltsakis et al. [19]), catalyst supporters (Ismagilov et al [20]), porous electrodes (Wilkinson and Paserin [21]), energy absorbers (Kim et al [22]), pneumatic silencers (Kang et al [23]), shock-absorbing buffers, electromagnetic shielding or compatible elements (Losito [24]), flame arresters, cellular scaffolds for tissue engineering (Spoerke et al [25]), flow mixers (Azzi et al [26]), etc. Furthermore, they can be used to produce composite materials or to serve as gaskets.…”

“…The results indicated that the friction factor is much lower for the fins with a high ppi value (40), despite the lower permeability, due to relatively larger surface area. For a constant ppi value (20), increasing the porosity resulted in a higher friction factor. (Even though the dimensional pressure drop decreased, the friction factor increased due to the sharp drop in surface area for higher porosities).…”

Abstract:Recent advances in manufacturing methods open the possibility for broader use of metal foams and metal matrix composites (MMCs) for heat exchangers, and these materials can have tailored material properties. Metal foams in particular combine a number of interesting properties from a heat exchanger's point of view. In this paper, the material properties of metal foams and MMCs are surveyed, and the current state of the art is reviewed for heat exchanger applications. Four different applications are considered: liquid-liquid, liquid-gas and gas-gas heat exchangers and heat sinks. Manufacturing and implementation issues are identified and discussed, and it is concluded that these materials hold promise both for heat exchangers and heat sinks, but that some key issues still need to be solved before broad scale

a b s t r a c tProcess intensification is a chemical engineering field which has truly emerged in the past few years and is currently rapidly growing. It consists in looking for safer operating conditions, lower waste in terms of costs and energy and higher productivity; and a way to reach such objectives is to develop multifunctional devices such as heat exchanger/reactors for instance.This review is focused on the latter and makes a point on heat exchanger/reactors. After a brief presentation of requirements due to transposition from batch to continuous apparatuses, heat exchangers/reactors at industrial or pilot scales and their applications are described.
