Abstract: 
In this work, the hydrogen evolution reactions on stainless steel electrodes in ultra-pure water (UPW) and water-based Fe2O3 and Zinc oxide colloid solutions have been investigated. Ultra-pure water with electrical conductivity (0.45μs) was used to synthesize Fe2O3 and ZnOnano colloidal using pulsed laser ablation of zinc metal in water. All experiments were performed using a Q-switched Nd-YAG laser operating at fundamental mode 1064nm with 9ns pulse duration, at fixed laser output energy (750mJ). Different number of pulses (750 and 1000) was applied with the aim to affect the concentration of synthesized Fe2O3 and ZnO colloidal. Hydrogen generator-fuel cell driven by 30 volts as input source is developed with Fe2O3 and ZnO Nano colloidal. Variation of Fe2O3 Nano concentration according to different number of pulses, which gives the maximum H2/O2 output of 1.2 mL/s.
