Downsized footprint and material changes for GM's fourth-generation fuel cell technology

Announcements in third and fourth quarters of 2006 by General Motors that it would create a test fleet of 100-plus Equinox fuel cell vehicles (FCVs) and road test its drivable Sequel concept FCV beginning in 2007, represent new benchmarks in the automaker's fuel cell technology history, dating back to 1968. GM's latest hydrogen-fueled PEM fuel cell system has been significantly downsized so as to achieve a cross-platform fit in multiple GM models.
