“…The failure of the samples might also be influenced by the angular pore shape, which acts as a notch for crack initiation and is more pronounced in Ti‐HDH powder. A more detailed study on the mechanical properties of porous titanium transport layers was recently published . In this study, the mechanical strength of the transport layers was investigated under more realistic conditions.…”

“…In addition, PEM electrolyzers can produce hydrogen at significant differential pressures vs the oxygen side, ranging from 15 to 100 bar (60, 61), with even higher pressures (up to 350 bar) having been tested (62). Under these conditions, the titanium PTL on the anode side is subjected to major mechanical stresses (63). A second challenge is to guarantee proper and homogenously-distributed contact pressure over the catalyst layer.…”

“…24 Therefore, developing low-cost manufacturing technology of Ti-based PTL or finding another inexpensive material [25][26][27] is necessary for commercialization. [28][29][30][31] Liu et al 28 studied PTL coating by the sputtering method. They coated a 20 to 150 nm thick iridium layer on the commercial titanium PTL to enhance the performance of PEMWE.…”
