The problem with micro cap stocks is that a pump on news doesn't last very long. FCEL dropped out of a pennant reversal, looks like it's going to fill that news gap.
I wouldn't buy until MFI goes oversold on the daily, probably headed below $ 2 again within the next 2 weeks. I said a few weeks ago that this wouldn't make it above $ 3 resistance, it only made it to $ 2.5. Old support is new resistance, will have a hard time breaking that again.
