Effect of gas flow channel structure on the performance of an anode-supported honeycomb solid oxide fuel cell
Autor: Hironori NAKAJIMA, Shunzaburo MURAKAMI, Tatsumi KITAHARA
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 84, Iss 859, Pp 17-00419-17-00419 (2018)
An anode-supported honeycomb SOFC gives high volumetric power density and improves thermo-mechanical durability at high temperatures. We have so far fabricated and tested a honeycomb cell with a cathode layer of LSM and an electrolyte layer of 8YSZ o

Water vapor exchange system installed in a polymer electrolyte fuel cell to enhance the performance without humidification
Autor: Tatsumi KITAHARA, Hironori NAKAJIMA, Kazuto TSUDA
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 80, Iss 820, Pp TEP0363-TEP0363 (2014)
Polymer electrolyte fuel cells (PEFCs) generally have external humidifiers to supply humidified hydrogen and oxidant gases, preventing dehydration of the membrane electrode assembly (MEA). If a PEFC could be operated without humidification, external

Analysis of water behavior in PEFC through 3D thermal and temperature distribution measurement by ultrafine thermocouples
Autor: Chiaki MIZUTANI, Tatsumi KITAHARA, Hironori NAKAJIMA, Kazunari SASAKI, Kohei ITO
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 80, Iss 820, Pp TEP0364-TEP0364 (2014)
Local water behaviors in a PEFC was analyzed by equivalent electric circuit and the temperature distribution with an ultra-fine thermocouples. The thermocouple is tailor-made: thermocouple elements in 50 μm diameter are welded, and electrically insu

(Digital Presentation) Effect of the Hydrophilic Layer in Double Microporous Layer Coated Gas Diffusion Layer on PEFC Performance
Autor: Peng Wang, Hironori Nakajima, Tatsumi Kitahara
Publikováno v: ECS Transactions. 109:85-93
The polymer electrolyte fuel cells (PEFCs) are commonly used in the vehicle industry, but the relatively higher costs of power generation limit the potential for further application. The PEFCs output power can be mainly undermined by the water manage
