I agree that cheap-but-intermittent renewable electricity calls for differently optimized electrolyzer designs. Optimize for "cheap to manufacture and maintain" so you can afford to use them at a low duty cycle. If that is the underlying objective for this research, it's great, but doesn't come through clearly in the linked report. They mention efficiency in the headline, efficiency 7 times more in the body, and cost only twice, only in the body.
