英语翻译
Microtubular solid oxide fuel cells (SOFCs) have been developed
in recent years mainly due to their high specifi c surface
area and fast thermal cycling.Previously,the fabrication of
microtubular SOFCs was achieved through multiple-step processes.[
1–3] A support layer,for example an anode support,is fi rst
prepared and presintered to provide mechanical strength to the
fuel cell.The electrolyte layer is then deposited and sintered
prior to the final coating of the cathode layer.Each step involves
at least one high-temperature heat treatment,making the cell
fabrication time-consuming and costly,with unstable control
over cell quality.For a more economical fabrication of micro-
tubular SOFCs with reliability and flexibility in quality control,
an advanced dry-jet wet-extrusion technique,i.e.,a phase
inversion-based coextrusion process,was developed.Using this
technique,an electrolyte/electrode (either anode or cathode)
dual-layer hollow fiber (HF) can be formed in a single step.
Generally,the electrolyte and electrode materials are separately
mixed with solvent,polymer binder,and additives to form the
outer and inner layer spinning suspensions,respectively,before
being simultaneously coextruded through a triple-orifi ce spinneret,
passing through an air gap and fi nally into a non-solvent
external coagulation bath.In the mean time,a stream of non-
solvent internal coagulant is supplied through the central bore
of the spinneret.The thickness of the two layers is largely determined
by the design of the spinneret and can be adjusted by
the corresponding extrusion rate,while the macrostructure or
morphology of the prepared HF precursor can be controlled by
adjusting coextrusion parameters such as suspension viscosity,
air gap,and flow rate of internal coagulant.The dual-layer HF
precursor obtained is then co-sintered once at high temperature
to remove the polymer binder and form a bounding between
the ceramic materials.In previous work,[4–6] a dual-layer HF
support for microtubular SOFCs,which consisted of an electrolyte
outer layer of approximately 80 μm supported by an
asymmetric anode inner layer with 35% fingerlike voids length,
was successfully fabricated using the coextrusion and cosintering
process.
