One of the key challenges in optimal operation of PEM hydrogen cells is to ensure optimal distribution of the liquid water inside them. Excessive accumulation of water can clog proton and electron ...

PEM fuel cells have good efficiency and low operating temperature and could play an important role in power generation in the future. They are currently the leading technology for automotive ...

Researchers at the University of Sevilla in Spain have developed a proton exchange membrane fuel cell (PEMFC) with a bipolar plate (BP) based on a nature-inspired structure. According to the ...

Mechanisms of the bulk and local oxygen transport in cathode catalyst layers (CCLs) in proton exchange membrane fuel cells (PEMFCs) are presented. State-of-the-art strategies to mitigate the oxygen ...

Early last September, the U.S. Federal Aviation Administration (FAA) made its first move to allow unmanned commercial aircraft—drones—to fly beyond the sight of their operators. The agency will begin ...
