It has been reported that the Ni anode electrode used in alkaline water electrolysis (AWE) is degraded when the fluctuating electricity produced by renewable energy (wind and solar power) systems is used. To develop alternative materials, we focused on zirconium oxide because of its high chemical stability, and investigated its catalytic activity for the oxygen evolution reaction (OER) on zirconium oxides on a zirconium plate fabricated by both air oxidation (ZrO2/Zr) and arc-plasma deposition (ZrO2/Zr_APD). From cross-sectional observations and electrochemical results, the mixed tetragonal and monoclinic structure of ZrO2 was related to its catalytic activity for the OER. ZrO2/Zr_APD showed obviously a higher activity than ZrO2/Zr. The reason for this is that the particles are better dispersed in ZrO2/Zr_APD than in ZrO2/Zr, so the electrochemical surface area of ZrO2/ Zr_APD seems to be larger than that of ZrO2/Zr.

Niobium-added titaniumoxide is a promising candidate as a substitute carbon support for cathodes ofPEFCs. Nb- added TiO2 can act as a support for platinum nanoparticles to enhance the oxygen reduction reaction (ORR) ac- tivity and durability under acidic conditions. Nb-added TiO2 supports with the desired surface area (10–130 m2 g−1) and conductivity (10−7–10−2 Scm−1) were prepared by changing the amount of Nb and the heat treatment conditions. First, we conducted a systematic investigation with changes in theamount ofniobium addition, heat-treatment temperature, and time under a pure hydrogen atmosphere to reveal the physicochem- ical factors that govern the surface area and conductivity. Finally, we successfully proposed a procedure to pre- pare highly durable Nb-added TiO2 supports with the desired surface area and conductivity by controlling the amount of niobium addition, heat-treatment temperature, and time under hydrogen. The charges of the double layer were almost unchanged after 5000 cycles of an accelerated durability test (ADT).
Practical and Reliable Methanol Concentration Sensor for Direct Methanol Fuel Cells

Language：English Publishing type：Research paper (scientific journal) Publisher：公益社団法人 電気化学会 Joint Work
An electrochemical methanol concentration sensor with practicality and reliability has been developed to apply for a direct methanol fuel cell (DMFC) system. The methanol concentration can be estimated simply by the original algorithm based on the Arrhenius law and diffusion limiting current, even though the complex oxidation current characteristics for the methanol concentration and temperature. The oxidation current of methanol shows linearity against the methanol concentration up to 10 wt% (15 mgPt cm<sup>−2</sup> at anode) with quick response. The sensor also has a high durability for 6500 h in the simulated DMFC operating temperature.

ELECTROCHEMISTRY 89 ( 2 ) 186 - 191 2021.1 [Reviewed]
Language：English Publishing type：Research paper (scientific journal) Publisher：公益社団法人 電気化学会 Joint Work
<p>For electrocatalysts of oxygen evolution reaction (OER), a new accelerated durability test (ADT) protocol is presented. The protocol is designed to closely mimic the fluctuations of renewable energies. The unit cycle of the current ADT protocol represents the "ON/OFF" operation mode. In the "ON" step, the electrolyzer operates under a DC current of 0.6 A cm<sup>−2</sup>. In the "OFF" step, the electrocatalyst is subjected to a constant potential that is clearly more cathodic than its OER onset potential (namely, 0.3, 0.5, and 0.7 V vs. RHE) for 10 or 60 s. The transition from the "ON" state to the "OFF" state occurs through a cathodic linear sweep voltammetry of a fast sweep rate to mimic the sudden changes in the renewable power. A NiCoO<i><sub>x</sub></i>/Ni-mesh electrode was used as a case study. The electrode showed remarkable durability under continuous operation (<i>i</i> = 0.6 A cm<sup>−2</sup>) for about 900 hours. However, it did suffer severe degradation after a certain number of ADT cycles, and the rate of degradation mainly depends on the potential value and the duration of the "OFF" step. Interestingly, the inclusion of the 10-sec open-circuit potential step after the "ON" step clearly mitigates the impact of energy fluctuations on the durability of OER electrocatalysts.</p>
