“…7 displays another potential advantage of ionized PVD electrolyte fabrication. Nano-crystalline YSZ has been observed to have increased ionic conductivity via increase grain boundary area as compared with bulk YSZ [20,21]. The stability of this nano-cystalline structure during thermal cycling to 1100°C in air provides encouraging evidence for its durable application as an SOFC electrolyte.…”

“…The success of this process was established with the achievement of 1.0 V OCV at 650°C [31]. Numerous significant progresses across the globe are discussed in various articles [3,[32][33][34][35][36][37][38][39][40][41][42][43][44][45][46].…”

“…Estes resultados têm grande importância, pois indicam que se obteve um filme denso, aparentemente sem trincas, com baixa rugosidade e com tamanhos de grãos distribuídos. Outra informação que apresenta elevada importância é o tamanho nanométrico do grão, pois diversos autores [22][23][24][25] têm citado a influência do tamanho do grão na condutividade elétrica de filmes de eletrólitos de YSZ, tendo a condutividade um aumento inversamente proporcional ao tamanho do grão. Foi mostrado que ocorre mudança de inflexão da curva de Ahrrenius da condutividade elétrica de filmes de zircônia dopada com céria quando eles possuem tamanho de grão em escala nanométrica, o que resulta também na alteração da energia de ativação e na facilidade de transporte de íons oxigênio [24,25].…”
