As concerns mount on limited energy sources and ecological
challenges, it is essential to develop alternative, renewable, and
environmentally friendly sources of energy to meet the changing
and growing global energy demands. Fuel cell, particularly proton
exchange membrane fuel cell (PEMFC) that is an electrochemical
device directly converting the chemical energy of a fuel into electricity,
emerges as a promising alternative to the depleting fossil
energy sources due to its green nature, high energy density, and
wide range of applicability including automotive and stationary
application [1,2]. Nonetheless, the durability of PEMFC remains a
major challenge towards its commercial viability and has attracted
great attention from researchers worldwide [3,4].
