A polymer electrolyte fuel cell life test: 3 years of continuous operation
- Simon Cleghorn, D. Mayfield, +5 authors U. Beuscher
- Chemistry
- 14 July 2006
Abstract Implementation of polymer electrolyte fuel cells (PEMFCs) for stationary power applications requires the demonstration of reliable fuel cell stack life. One of the most critical components… Expand
Analysis of GDL flooding effects on PEMFC performance
- S. Shimpalee, U. Beuscher, J. Zee
- Materials Science
- 1 August 2007
One of the major concerns of the gas diffusion layer (GDL) inside a proton exchange membrane fuel cell (PEMFC) is water management. Treatment of the pores of the GDL can affect the PEMFC performance… Expand
The permeation of binary gas mixtures through support structures of composite membranes
- U. Beuscher, C. Gooding
- Chemistry
- 11 November 1998
Abstract The dusty gas model (DGM) is used to describe transport of binary gas mixtures through porous membrane supports to quantify the resistance towards permeation. The model equations account for… Expand
Experimental Method to Determine the Mass Transport Resistance of a Polymer Electrolyte Fuel Cell
- U. Beuscher
- Materials Science
- 1 September 2006
A technique to measure an average mass-transport resistance of a polymer electrolyte fuel cell in situ is described. Experimental polarization curve data are extrapolated to the limiting current, at… Expand
Transport Phenomena in Elevated Temperature PEM Fuel Cells
- P. Sinha, C. Wang, U. Beuscher
- Chemistry
- 2007
There is a recognized need for operation of polymer electrolyte membrane (PEM) fuel cells at higher than 80°C for automotive applications. Electrochemically, higher temperature results in better… Expand
Interplay among membrane properties, protein properties and operating conditions on protein fouling during normal-flow microfiltration
- ShyTyug Loh, U. Beuscher, +4 authors S. R. Wickramasinghe
- Chemistry
- 15 April 2009
Abstract Normal-flow filtration is used frequently in the biopharmaceutical industry for applications such as sterile filtration of fermentation media, buffers and product proteins. Though the… Expand
The influence of the porous support layer of composite membranes on the separation of binary gas mixtures
- U. Beuscher, C. Gooding
- Chemistry
- 6 January 1999
Abstract Thin film composite (TFC) membranes exhibit a high flux for gas and vapor permeation and are viable for a wide range of applications. The high flux may also increase the importance of the… Expand
Nonisothermal Modeling of Polymer Electrolyte Fuel Cells II. Parametric Study of Low-Humidity Operation
