Mechanical Properties of Ni-YSZ Cermet Anode under SOFC Operating Condition by Using In-Situ Mechanical Testing Method

WATANABE Satoshi

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A 78(787) 349-360 Apr 2012

Ni-YSZ composites are widely used as SOFC anode materials for electrochemical devices. The mechanical properties of Ni-YSZ composites were investigated by using a Small Punch(SP) testing method under SOFC operating condition. The compositions of t...

Radiative heat transfer enhancement using geometric and spectral control for achieving high-efficiency solar-thermophotovoltaic systems

Asaka Kohiyama, Makoto Shimizu, Hiroo Yugami

Japanese Journal of Applied Physics 57 Apr 2018

© 2018 The Japan Society of Applied Physics. We numerically investigate radiative heat transfer enhancement using spectral and geometric control of the absorber/emitter. A high extraction of the radiative heat transfer from the emitter as well as ...

Creep Property of Cathode Materials Based on Lanthanum Manganite in SOFC Operating Conditions

IGUCHI Fumitada, KAWADA Tatsuya, YUGAMI Hiroo

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A 78(788) 523-530 Jun 2012

Creep properties of strontium doped lanthanum manganite (LSM) were studied in SOFC operating conditions, i.e. in the temperature range of 800°C to 1050°C and in air and argon gas environment. Although the difference of atmosphere did not affect cr...

Spectrally shaping high-temperature radiators for thermophotovoltaics using Mo-HfO<inf>2</inf>trilayer-on-substrate structures

Etienne Blandre, Makoto Shimizu, Makoto Shimizu, Asaka Kohiyama, Hiroo Yugami, Pierre Olivier Chapuis, Rodolphe Vaillon, Rodolphe Vaillon

Optics Express 26 4346-4357 Feb 2018

© 2018 Optical Society of America. Easy-to-fabricate, high-temperature, thermally-stable radiators are critical elements for developing e cient and sustainable thermophotovoltaic energy conversion devices. In this frame, a trilayer-on-substrate st...

Mechanical Properties of Anode Materials Based on Ni-YSZ in SOFC Operating Conditions

KITAHARA Hiromichi, IGUCHI Fumitada, OKUDA Tomonori, SATA Noriko, KAWADA Tatsuya, YUGAMI Hiroo

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A 78(792) 1198-1207 Sep 2012

Mechanical properties of Ni-YSZ cermet (Ni 30, 44, 58 vol.%) in SOFC operating conditions in the temperature range of room temperature to 1000°C and in reduction atmospheres, were studied by an in situ four points bending method. Ni30 specimens in...
