  3. 2. The effect of material properties on PEM fuel cell catalysts on durable oxidation reduction activity

    Master-uppsats, KTH/Kemiteknik

    Författare :Xiaoling Jiang; [2023]
    Nyckelord :PEM fuel cell; catalyst; ORR activity; particle size; degradation; PEM-bränslecell; katalysator; syrgasreduktionsaktivitet; partikelstorlek; åldring;

    Sammanfattning : I detta examensarbete utforskas påverkan av partikelstorleken hos Pt-katalysatorer på kolbärare på syrereduktionen i polymerelektrolytmembran (PEM)-bränsleceller. Den elektrokemiskt aktiva ytarean, aktiviteten för syrereduktion och tillhörande degraderingshastigheter för de undersökta katalysatorerna beräknas och jämförs. LÄS MER
