According to today's PE Week Wire, solid oxide fuel cell developer Ion America has raised a $102mm Series D, plus $2mm in convertible securities. According to the same mention (based on regulatory findings), the post-money valuation on their 2004 $45mm Series C round was $114mm (no word on the valuation of this new round). This brings the company's venture funding to $165mm in total to date. Kleiner Perkins, Mobius and NEA are backers. We last saw news about Ion America this time last year... The company still appears to be in official stealth mode, without a public website.
