Experimental investigation of electrolytic solution for anion exchange membrane water electrolysis
Hiroshi Ito,Natsuki Kawaguchi,Satoshi Someya,Satoshi Someya,Tetsuo Munakata,Tetsuo Munakata,Naoki Miyazaki,Masayoshi Ishida,Akihiro Nakano +8 more
TL;DR: In this paper, the effect of species and concentration of electrolytic solution on the performance of anion exchange membrane (AEM) water electrolysis is experimentally examined, and it is shown that the performance with K2CO3 solution is superior to that with KOH solution, even at a similar pH of around 12.

Efficiency of unitized reversible fuel cell systems
TL;DR: In this article, a pilot-scale unitized reversible fuel cell (URFC) system was installed in a laboratory (AIST) and its efficiency was comprehensively evaluated by considering the amount of recovered heat during EL and FC modes assuming combined heat and power (CHP) applications.
