“…As Pd absorbs hydrogen, its lattice expands. As the hydrogen content increases, a b-PdH x phase is formed, which is thermodynamically unstable under ambient conditions; therefore, it spontaneously converts to thermodynamically stable a-PdH y phase releasing heat and hydrogen [1]. During this process, cracks are formed to release the built-up stress from the lattice contraction.…”

“…In the current study, Pd was preferred as the secondary catalyst at the anode support (AS) because of its superior catalytic activity for SR, according to many published studies. 33,[40][41][42][43] Moreover, based on the phase diagram of the Pd-Ni binary alloy system, 44 depicted in Figure S1, a Pd-Ni solid solution can be formed across all compositions even at LT; thus, the catalytic activity of the anode can be further enhanced by forming Pd-Ni alloys. [45][46][47][48] Therefore, in this study, the effect of a Pd catalyst in TF-SOFCs for butane DISR (denoted as B-DISR) operation can be expected and exhibited by the infiltration process that was successfully established in our recent studies.…”

Improved electrochemical performance and durability of butane‐operating low‐temperature solid oxide fuel cell through palladium infiltration

Low-operating-temperature solid oxide fuel cells (LT-SOFCs) with various kinds of fuel, such as hydrocarbons, biogas, natural gas, and oxygenated fuel has been an active SOFC research topic. However, conventional SOFC anodes comprised of nickel metal and yttria-stabilized zirconia composite (Ni-YSZ) experience rapid degradation when operated for the butane direct internal steam reforming (B-DISR), especially at a low temperature (LT) range. This study reveals that the impregnated Pd into the Ni-YSZ anode support of thin-film SOFCs (TF-SOFCs) is effective for achieving better performance and stability regarding the TF-SOFC in B-DISR at 600 C. Adding Pd as a dopant into Ni-YSZ significantly promotes the catalytic activity due to the Pd-Ni alloy formation, both on the YSZ grain and the Ni grain surface. The electrochemical performance of cells without Pd (Ni-YSZ cell) and a Pd-infiltrated Ni-YSZ anode (Pd-Ni-YSZ cell) are compared at 600 C for the B-DISR mode at a ratio of steam-to-carbon of 3. Finally, longterm durability tests were performed at 600 C and under 0.15 A cm −2. The Pd infiltration decreases the deterioration rate to 0.63 mV h −1 after the first 80 hours of operation for the Pd-Ni-YSZ cell, which was a significant improvement from that of the Ni-YSZ cell, 3.75 mV h −1 after 40 hours of operation.

“…The deposition method determines the subsequent calibration routine as deposition methods can be divided into methods, which are characterized by a co-deposition of hydrogen and fabrication routes that ensure a hydrogen-free film. Electrodeposition usually comprises the co-deposition of hydrogen into the deposited palladium layer [69]. Electroless deposition can be also accompanied by hydrogen formation [70].…”

Influence of oxygen concentration in the measurement atmosphere on detection of hydrogen using Kelvin probe was studied. The studied material was a 100-μm-thick palladium foil, which was mounted in a 3D printed electrochemical flow cell. The used setup enables hydrogen loading with in-situ contact potential measurement of the hydrogen exit side of the Pd electrode. The hydrogen loading and unloading procedure, including insertion of different amounts of hydrogen into the Pd membrane and recording resulting values of contact potential difference, was performed at distinct oxygen concentrations ranging between 1 and 80 vol%. An increasing amount of oxygen in the atmosphere surrounding the hydrogen-loaded Pd electrode resulted in an accelerated removal of hydrogen from the Pd. The kinetics of this reaction was studied based on Kelvin probe measurements, and a reaction mechanism is discussed.
