I feel it's exactly like you say it. The UNIST team are the ones who came up with this technology and they combined their tech with HYSR's oxygen catalyst because it's one hell of an accomplishment and low cost. 75% efficiency of Iridium with abundant materials and a goal of 90%?. The fact that their flirting with that number, especially with so little r&d is ridiculous and also why Jong Baek and his team are brainstorming with our HYSR team.
Best oxygen catalyst combined with best hydrogen catalyst and a few more tweaks = cost competitive hydrogen generator. imho
