With this respect Ln2NiO4+¿ (Ln=La, Pr or Nd) compounds with the K2NiF4 type structure act as alternative cathode materials for IT-SOFC due to their mixed ionic and electronic conductivity (i.e. MIEC properties). Pr2NiO4+¿ shows excellent electrochemical properties at intermediate temperature (i.e. low polarization resistance Rp value, Rp = 0.03 ¿.cm² at 700 °C), while La2NiO4+¿ exhibits higher chemical stability. So, the properties of La2-xPrxNiO4+¿ nickelates were investigated with the aim to find best compromise between chemical stability and electrochemical performances. As an interesting point, even after complete dissociation of Pr2NiO4+¿ into PrNiO3-¿, Pr4Ni3O10+¿ and Pr6O11, the polarization resistance does not show significant change. So finally, two new materials PrNiO3-¿ and Pr4Ni3O10+¿ were investigated as SOFCs cathode showing very promising results for Pr4Ni3O10+¿ in symmetrical cell (Rp (Pr4Ni3O10+¿) = Rp (Pr2NiO4+¿) = 0.15 ¿.cm² at 600 ° C) and single cell (1.6 W.cm-2 at 800 °C).\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659977305\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659977305","offer_id":39441572921437,"sku":"9783659977305","price":74.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/1eb00f28-4330-46c1-89c5-ab7c3aa07a66.jpg?v=1772865274","url":"https:\/\/shop.autorenwelt.de\/products\/stability-aging-studies-of-pr-based-nickelates-as-cathodes-for-sofc-von-vaibhav-vibhu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
