Their efforts include not only finding methods to raise the activity of the catalyst so less can be used for the same power output but also determining how to form a stable catalyst structure that does not degrade over time and avoiding side reactions that contaminate the membrane 他们不仅致力于寻觅提升触媒活性的方法，好以较少的用量达到相同的输出动力，还尝试做出不会经时耗损，又能避免次反应污染隔膜的安定触媒结构。
