GEOMAR earlier this year tested fuel cell technology for use on a long-term sea? oor observatory, where it could also be required to power robotics. GEOMAR’s solution is a fuel cell, developed in partnership with the Centre for Solar En- ergy and Hydrogen Research, Ulm (ZSW), as part of the Ger- man Federal Ministry of Economics and Technology funded

ARIM-FUEL project (ARIM stands for “Autonomous Robot- ic Sea-Floor Infrastructure for Bentho-Pelagic Monitoring”). costs a modest $1250. The system can deliver 150 W to 1kW
