• group [10][12]. The regular arrangement of functional groups on the nanocapsule surface can provide nucleation and structure-directing centers for the controlled crystallization of metal-oxide particles. We have chosen cerium(IV) oxide nanoparticles to be deposited on the nanocapsule surface in order to

• combine biocompatibility with a high oxygen-scavenging ability. Cerium oxide is a lanthanide metal oxide with a redox potential behavior that can easily switch between cerium(IV) and cerium(III) and has the capability to leave oxygen vacancies in the crystal lattice [39]. Cerium(IV) oxide exhibits

• excellent antioxidant properties, ideal for applications such as water-gas shift catalysis [40], combustion catalysis [41], oxygen ion conductors, and solid-oxide fuel cells [42]. Due to the valence and oxygen defect properties of cerium(IV) oxide, nanoparticles of this material are also used as efficient

• deposition process. This result is interpreted in the light of the contributions of different energy components (surface energy and elastic modulus) which act dependently on the substrate properties, such as its nature and structure.

Compared to conventional power sources, fuel cells offer higher efficiencies, lower emissions, modular installation

• compared to cells with untreated anodes and anodes with ceria coatings deposited after the sulfonate pretreatment. Possible explanations for the effects of the treatments on the structure of the coatings, and for the effects of the coatings on the performance of the cells, are discussed. Keywords: cerium
