evaporate/heat it till crystallization point. Obtain dry crystals.

By the way...u guyz missed the working of hydrogen fuel cells with acid electrolyte..

heres. it..

the hydrogen (H2) loses electrons.. 2H2 --> 4H+ + 4e- which travel through the circuit to the cathode and react with O2..also the H+ ions from the acid electrolyte meets the electrons and O2 at the cathode

the reaction

O2 + 4H+ + 4e- = 2H2O

---
The H+ ions removed from the electrolyte are replaced by those produced at the anode.

@adorabledaughter - yea..ut u can use the word heat and crystallization point.
