The AEMHY anion exchange membrane (AEM) electrolyzer uses non-precious-metal catalysts and the QZ-AEM membrane developed in-house. It offers a wide load range and high reliability for renewable hydrogen production, industrial green hydrogen and distributed hydrogen projects. The stack family is organized by single-cell active area into three series, covering hydrogen output from 2 Nm³/h to 200 Nm³/h.
Series Overview
| Series | Single-cell active area | Maximum hydrogen output | Model | Typical application |
|---|---|---|---|---|
| Small | 100 cm² | 4 Nm³/h | QZC-2 (2 Nm³/h), QZC-4 (4 Nm³/h) | Laboratory testing, distributed hydrogen, demonstration projects |
| Medium | 400 cm² | 40 Nm³/h | QZC-40 | Industrial on-site hydrogen, industrial park supply |
| Large | 2500 cm² | 200 Nm³/h | QZC-200 | Large-scale green hydrogen, solar and wind coupled projects |
