[285]. However, although seriousperformance degradationand even failure of the cell structure were not observed during experimental stability tests primarily due to the limited operation duration restricted by the amount of carbon fuel as well as the assistances ofhigh current densityand necessary high...
The thermodynamic exergy (the amount of work a system can perform when it is brought into thermodynamic equilibrium with its environment [32]) is introduced to unify the two energy forms of bleed air and electric power extraction. The exergy value of the electric power is equal to the amount...
Affordability High ratio between cost of fuels and household incomes, including role of tax systems or assistance schemes. Inability to invest in the construction of new energy infrastructures. External/internal Flexibility Inability to move to a form of energy service provision that is appropriate to...
Accardo et al. [57,58] added nano-zirconia particles into a Ni–Al anode to improve its performance in MCFC application. During the ball milling and sintering processes, the zirconia nanoparticles were incorporated into the NiAl particles, effectively interacted with the cubic structure of Ni–Al ...
We are also thankful to Henrik Paulsen for assistance in preparing samples for SEM/EDS analyses. We thank Enzo Moretti, Ilaria Ritucci, and Ragnar Kiebach for improving the images of the monoliths. We are grateful to Søren Christensen for assisting with the preparation of slurries for tape ...

Both theories can make helpful assistances to better understand the proton conduction mechanism in PEMs. The proton transfer happens with a ‘vehicle’ or proton solvent (for example, water molecules as hydrates in the PEM molecular structure) that provides a suitable diffusion rate in the ‘...
