Hydrogen fuel single cell test fixture

The T3-125S and T3-125E fixtures from Canrd are precision tools developed for hydrogen‑oxygen fuel cell single‑cell testing, specifically designed to characterize membrane electrode assemblies (MEAs). These fixtures enable reliable measurement of polarization curves, AC impedance, electrochemical active surface area, hydrogen crossover current density, as well as activation and ohmic polarization overpotentials. Built for high reproducibility and long service life, they simplify assembly while maintaining consistent contact and sealing across the test cell. The T3-125S is the standard version suited for comprehensive electrochemical analysis, while the T3-125E reduced version offers a cost‑effective option for routine screening. Both models are widely adopted in R&D laboratories working on catalyst evaluation, MEA development, and performance optimization of proton exchange membrane fuel cells. Their robust construction ensures stable data acquisition under varying operating conditions, making them a practical choice for researchers focusing on fuel cell diagnostics and materials assessment.
