Long ago and far away, I was a frequent MATLAB user for Engineering applications. Fast forward a few decades and as a Transportation Tech faculty member, I am using many of the Simscape models to reinforce learning that is difficult, or very expensive, to explore in actual EVs & Hybrid EVs. 
The Fuel Cell Reference Application model documented here is fantastic, but I am not experienced enough with Simulink to understand how to get the same variables that are shown in the  Performance & FE Scope view exported to SDI. The learners in my classes, Automotive Tech students at a Tech College, absolutely see value in exploring data in SDI! Not so much in manipulating data in underlying MATLAB!  Thank you for pointers in getting these 8 vectors accessible for SDI.  These variables do not appear when I launch SDI after the simulation runs.
