“…Although, other classes of oxides (Ruddlesden–Popper, double perovskite, fergusonite/scheelite structures) also display proton transport, they concede to perovskite-structured phases in terms of achieving both high absolute levels and contributions of proton conductivity. 29,30 Due to this fact, BaCeO 3 , BaZrO 3 or their solid solutions (BaCeO 3 –BaZrO 3 or Ba(Ce,Zr)O 3 ) represent the most frequently-used basic oxides 31–36 for designing electrolyte membranes used in protonic ceramic fuel cells (PCFCs), protonic ceramic electrolysis cells (PCECs), protonic ceramic converters (PCCs), protonic ceramic pumps (PCPs), and protonic ceramic sensors (PCSs). As can be seen from Fig.…”

“…From our group's previous study, 29 tritium concentration, that is, hydrogen solubility or dissolution was estimated to be around 1.8 mol% and remained almost constant through the temperature range of 400-600°C in 10% Y-doped BaCeO 3 (BaCe 0.9 Y 0.1 O 3−α ). As deuterium used as fuel along with tritium in a nuclear fusion reactor and BaCe 0.9 Y 0.1 O 3−α shows better proton conductivity among other perovskites, 12,30,31,32,33,34 it is necessary to evaluate the deuterium dissolution, release, solubility, and diffusivity behaviors both in deuterium gaseous (e.g., D 2 ) and deuterium vapor (e.g., D 2 O) atmospheres for BaCe 0.9 Y 0.1 O 3−α .…”

“…4 Proton conducting oxides has the capability to operate at high-temperature environment with high proton conductivity. [5][6][7] Due to these reasons, proton conducting oxide is a candidate functional material in nuclear fusion reactor's various electrochemical devices such as hydrogen pump, hydrogen sensor, hydrogen gas separator, [8][9][10][11][12] tritium recovery system, 5 and tritium monitoring system. 13,14 Figure 1 shows a conceptual diagram of a tritium recovery system using proton conductive oxides.…”

Oxides having a perovskite structure are known to exhibit good proton conductivity in a high-temperature region, which makes them potential candidates in the tritium recovery and purification system of the electrochemical devices of fusion reactors such as hydrogen pumps, hydrogen sensors, and tritium monitoring systems. But the dissolution of hydrogen into the proton conductor and its release behavior is not well known yet. In this study, the dissolution and release behavior of hydrogen was investigated in BaCe 0.9 Y 0.1 O 3−α proton conductor by exposing deuterium gas (D 2 ) and heavy water vapor (D 2 O) at 600 or 700°C for 5 h. The dissolved deuterium amount in the sample was measured using a temperature-programmed desorption analysis (TDS) method. The relationship between the amount of deuterium dissolved in the sample with the exposure pressure was also investigated. At room temperature (RT), the diffusivity of hydrogen (e.g., deuterium) was calculated from the change of the amount of residual hydrogen in the exposed sample due to the change of storage time. The Tritium Migration Analysis Program, Version 4 (TMAP4) simulation code was used to simulate and compare the experimental value of the obtained diffusivity. Although diffusivity at RT has not been reported in the past, the diffusivity is close to the extrapolation value of the literature data. From the comparison of this research results with literature, it may consider that the dominant diffusion mechanism does not change regardless of the temperature range.

“…A proton-exchange membrane fuel cell (PEMFC) has a membrane between the cathode and anode that only allows protons to cross. Because the process is highly efficient, silent, and environmentally friendly, it has become the focus of recent research and development [1][2][3]. The energy conversion in a PEMFC strongly depends on the proton conductivity of the membrane.…”

Maintaining the performance of a fuel cell stack requires appropriate management of water in the membrane electrode. One solution is to apply an external humidifier to the supply gases. However, the operating conditions change continuously, which significantly affects the humidifier performance and supply gas characteristics. A straightforward humidifier module is needed for integration with the fuel cell system model. In this study, a lumped-mass model was used to simulate a hollow-fiber membrane humidifier and investigate the effects of various input conditions on the humidifier performance. The lumped-mass model can account for heat transfer and vapor transport in the membrane bundle without losing simplicity. The humidifier module was divided into three parts: a heat and mass exchanger in the middle and two manifolds at the ends of the exchanger. These components were modeled separately and linked to each other according to the flow characteristics. Simulations were performed to determine the humidifier response under both steady-state and transient conditions, and water saturation was observed in the outlet manifold that may affect the humidifier performance. The findings on the effects of the operating conditions and humidifier dimensions on the cathode gas can be used to improve humidifier design and control.
