load variation

Guys, I'm using a fuel cell stack model of simulink. And as a load I'm using a controlled current source. For this current I'm using a step as the input. 0-2->100A 2-10->120A. But some mistake happens in the fuel cell model of simulink when I do this. I wanna know why of this. What I'm doing is just a load variation.

Without a model we can only speculate. May be worth checking the built-in examples in Simscape Electrical. A good starting point is:
