Fuel cells are viewed as potential candidates for auxiliary power,
mobile power, stationary distributed or central power, and portable
product power. Solid oxide fuel cells are among the most efficient and
cost-effective. Although relatively high operating temperature limits
the range of applications possible, stationary, mobile, and even
portable product configurations are possible. The global solid oxide fuel cell (SOFC) market totaled $380 million in
2011, and is expected to hold a value of $530 million in 2016,
increasing at a five-year compound annual growth rate (CAGR) of 6.9%.
