Proton conductors for heavy-duty vehicle fuel cells
Autor: Emory S. De Castro, Hongfei Jia, Calum R. I. Chisholm, Yu Seung Kim, Craig S. Gittleman
Publikováno v: Joule. 5:1660-1677
Summary Fuel cells utilize the chemical energy of liquid or gaseous fuels to generate electricity. As fuel cells extend their territory to include heavy-duty vehicles, new demands for proton conductors, a critical component of fuel cells, have emerge

Highly Accelerated Stress Testing of Proton Exchange Fuel Cell Membranes for Heavy Duty Transportation Applications
Autor: Yeh-Hung Lai, Joseph D. Fairweather, Craig S Gittleman
Publikováno v: ECS Meeting Abstracts. :1525-1525
According to the US DOE’s multi-year Fuel Cell research, development, and demonstration plan, a 30,000 h lifetime, approximately four times that of the light-duty vehicles (LDV), is required for Heavy Duty Vehicle (HDV) applications [1]. Thus, high

Materials research and development focus areas for low cost automotive proton-exchange membrane fuel cells
Autor: Craig S. Gittleman, David A. Masten, Wenbin Gu, Anusorn Kongkanand
Publikováno v: Current Opinion in Electrochemistry. 18:81-89
Research and development of fuel cell materials often focuses on designing and discovering materials which will reduce the cost or improve the durability of an individual subcomponent. Examples of recent focus areas include non-Pt group metal catalys

Effects of melt flow index and equivalent weight on the dimensional stability and mechanical behavior of perfluorosulfonic acid ionomer membranes
Autor: Craig S. Gittleman, Ruichun Jiang, Yongqiang Li
Publikováno v: Journal of Power Sources. 478:228734
The effect of melt flow index (MFI) and equivalent weight (EW) on three aspects relating to perfluorosulfonic acid membrane mechanical durability were studied: dimensional stability, hygral stress during humidity cycles and resistance to rupture unde
