  Despite huge investment and efforts in the last decades, fuel cells are still
known as a fledgling industry after 170 years of the first fuel cell. It
becomes clear that these investment and efforts did not address the critical
questions. Why upscaling of fuel cells failed often when many researchers
stated their successes in small scale? Why the fuel cells with simpler
structure still lag far from the internal combustion (IC) engines and gas
turbines? Could the current investment of the hydrogen infrastructure reduce
substantially the fuel cell cost and make a breakthrough to the key issues of
durability, reliability and robustness? In this paper, we study these
fundamental questions and point out a must-way possible to reduce cost of fuel
cells and to substantially improve durability and reliability.
