Current density distribution in PEFC
Journal of Power Sources, 2005Abstract The determination of the current distribution in a polymer electrolyte fuel cell (PEFC) is of great practical importance to optimize the process parameter such as the flow field design, the humidification of reaction gases and the utilization of the fuel gas. In this paper, subcells approach is used to measure current density distribution in

Oxide-Supported PEFC Electrocatalysts
ECS Meeting Abstracts, 2015Even after the start of the commercialization of fuel cell vehicles from December 2014, further improvement of PEFC electrocatalysts is still desired for the next-generation PEFCs. While the Pt-based electrocatalyst supported on carbon black is the state-of-the-art material, further development using alternative electrocatalyst support materials are ...

Relations of Water Management and Degradation Processes in PEFC
ECS Transactions, 2008The life-time of fuel cells is one of the most critical issues for the commercialization of fuel cells. The decrease of the performance induced by the degradation of the fuel cell components together with failure which yield in the loss of the fuel cell functionality are the processes which limit the fuel cell life-time.

Modeling of the current limitations of PEFC
AIChE Journal, 2006AbstractPEFC operation in the regime of limiting current has been considered. The phenomenon of oxygen depletion on the cathode is considered responsible for the highest current limits of the cell. The performance of the cell appears to depend strongly on the geometry of the gas diffuser and supply channels.

A System Analysis on PEFC-CGS for a Farm Household
2008Since 2005, the Japanese government has had great efforts to promote PEFC-CGS (Polymer Electrolyte Fuel Cell Co-generation System) to a household sector in order to mitigate CO2 emissions. Because of this situation, there is a plan in which 480 units of 1kW PEFC-CGS for a household sector will be installed. However, the heat supply through PEFC-CGS can
