abstract = {In this study, a composite made of a porous stainless steel
(SS) 316L substrate coated with Nb was investigated as a
novel porous transport layer (PTL) for proton exchange
membrane electrolysis cells (PEMECs). The fabrication of
such SS316L/Nb composites using scalable and automatable
powder metallurgical techniques as tape casting,
screen-printing and field assisted sintering
technology/spark plasma sintering (FAST/SPS) was described.
Sintering behaviour and the interdiffusion at the SS316L/Nb
interface were investigated. Powder metallurgical techniques
such as screen-printing are the preferred method to achieve
a porous Nb coating, while FAST/SPS is the preferred method
for a better control of the SS316L/Nb interface by lowered
interdiffusion. First electrochemical performance tests with
SS316L/Nb composites demonstrate they have potential to
replace the state-of-the-art titanium-based PTLs. The use of
SS316L is expected to decrease manufacturing costs of PTLs,
while the addition of niobium layer, due to its excellent
corrosion resistance in acid environment, aims to improve
PEMECs lifetime and performance.},
