Analysis of a hybrid system combining solar-assisted methanol reforming and fuel cell power generation

•Hybrid system with PEMFC and solar photovoltaic-thermochemical reforming of methanol is proposed.•A novel hydrothermal management method involving methanol and water as coolants is proposed.•The exergy of hybrid system improves by 76.36% compared to the solar thermochemical system.•The efficiency of hybrid system can reach up to 59.15% at the highest efficiency of the PEMFC.
