A team including scientists at the National Institute of Standards and Technology (NIST) may have overcome a significant hurdle to manufacturing hydrogen fuel cells by creating a way to check whether the expensive catalysts the cells need have been incorporated quickly and effectively. Improved measurement methods are key to bringing hydrogen power a step closer to economical mass production.   [출처] nextBIGFUTURE, 2017.10.21. https://www.nextbigfuture.com/2017/10/fast-measuring-of-fuel-cell-printing-will-enable-economical-mass-production.html
