HERS-G3000 is a 3000 W methanol reforming high-temperature PEM fuel cell power system independently developed. It is a standardized module for distributed generation and CHP systems. Using methanol/water as fuel, on-line methanol reforming produces crude hydrogen at about 70% purity, which is fed directly to the HT-PEM stack—hydrogen is generated in situ and used as produced. The product combines efficient power generation with waste-heat utilization. Rated electrical output is 3000 W, electrical efficiency ≥42%, and CHP overall efficiency ≥90%. Advantages include low carbon, stable operation, flexible deployment, and a high level of integration.
