What it is
A bench-scale hydrogen energy system built and operated end-to-end: sodium borohydride (NaBH₄) hydrolysis generates hydrogen on demand, a purification stage cleans it to fuel-cell grade (CO < 10 ppm), and a PEM fuel cell delivers the electricity.
Highlights
- Designed, assembled, and ran the full chain — reactor, purification, fuel cell, and instrumentation
- The reaction is strongly exothermic (≈ −210 kJ/mol H₂), so thermal management decides system stability
- Fuel cell characterized with IV curves and EIS — CO poisoning shows up in impedance before any visible power loss
- Integrated operation revealed thermal coupling effects that never appear in isolated component tests
- The validated thermal model became the basis for the follow-up simulation study
Quantitative results withheld pending publication.
