Fuel cell X-ray study details effects of temperature and moisture on performance
Berkeley CA (SPX) Nov 17, 2017
Like a well-tended greenhouse garden, a specialized type of hydrogen fuel cell - which shows promise as a clean, renewable next-generation power source for vehicles and other uses - requires precise temperature and moisture controls to be at its best. If the internal conditions are too dry or too wet, the fuel cell won't function well. But seeing inside a working fuel cell at the tiny scales relevant to a fuel cell's chemistry and physics is challenging, so scientists used X-ray-based imaging tech ... read more
