Performance evaluation of PEFC stack

open access: yes, 1996
Polymer electrolyte fuel cells (PEFCs) have many advantages such as high current density, short start-up time and endurance for start-stop cycles. Making use of these advantages, Fuji Electric has been working with the Kansai Electric Power Co., Inc. to explore practical applications of PEFCs for an electric utility use.

Have significant biodiversity values been protected from industrial logging across Australia?

open access: yesConservation Science and Practice, Volume 7, Issue 8, August 2025.
Abstract Much of the planet's forest biodiversity is at risk from a range of threats. Threats include gaps in the protected area network and instances where these gaps are subject to intensive industrial logging. These gaps are referred to as optimal areas for protection and we sought to determine if certification schemes maintained the environmental ...

Development of PEFC for transportable applications

open access: yes, 1996
Since FY1992, we have been developing PEFC technologies under NEDO`s R&D program. High power density and rapid start-up are essential requirements for transportable applications. Also, if reformed gas is used as fuel, the prevention of CO poisoning and improvement of response to loading are essential.

Proton Conduction of a Hydrothermally Synthesized Hexaazatriphenylene‐Based Covalent Organic Framework

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 11, June 9, 2025.
A quinone‐functionalized hexaazatriphenylene‐based covalent organic framework (HAQ‐COF) is synthesized, making HAQ‐COF a promising polymer electrolyte membrane material for polymer electrolyte fuel cells. HAQ‐COF exhibits high water retention at room temperature and atmospheric pressure, along with high thermal stability.
