This 12 month feasibility project, led by UPS Systems plc, one of the UK’s leading standby power supply and fuel cell system integration companies examines the feasibility of developing a fully modular, methanol fuel cell system (DMFCs) for application within the mid-range boat and yacht sector. DMFC stacks with a 250W power output capability will be supplied under sub-contract by Baltic Fuel Cells GmbH. The modular approach is designed to meet the unmet market need for a marine proofed low-noise, low-emission auxiliary power supply, configured to allow self-maintenance with easy replaced components and integrated into existing on-board computer systems both to monitor/measure power output and to diagnose system failure with in-built maintenance instructions. Methanol based fuel cell are appropriate for marine application because of their light-weight and fuel storage requirements. Current DMFC systems do not have the required power output
