Proton conductor electrolytic cell composite membrane, membrane electrode and preparation method
The invention discloses a proton conductor electrolytic cell composite membrane, a membrane electrode and a preparation method, and belongs to the field of fuel cells and electrolytic cells. The composite membrane consists of a proton conductor-based electrolyte layer, a zirconium oxide-based electrolyte membrane layer and a cerium oxide-based electrolyte membrane layer which are tightly connected in sequence, the proton conductor-based electrolyte layer is made of BaZr1-zNzO3, and z is greater than or equal to 0.01 and less than 1; the material of the zirconia-based electrolyte membrane layer is MyZr1-yO2, wherein y is more than or equal to 0.01 and less than or equal to 0.5; the material of the cerium oxide-based electrolyte membrane layer is LnxCe1-xO2, wherein x is greater than or equal to 0.01 and less than or equal to 0.5. The composite membrane-based electrolytic tank has very low proton transmission resistance and relatively large electron blocking resistance, and shows excellent electrolytic performance at 400-600 DEG C.
