摘要: Abstract Every time a new material or component for technology is developed, it must be tested before can mass produced. Regarding polymer electrolyte membrane fuel cells (PEMFC), if its testing in single cell required validating effectiveness, optimizing performance terms of efficiency and endurance. To perform the testing, necessary to build electrode assembly (MEA). This argument this chapter, wherein review, integrated with personal experience, possible preparation methods laboratory-scale application reported. The goal supply information that define detailed procedure efficient MEA production.
