The demonstration campaign should include the transportation of the fuel cell system, its installation and test at end-user site for at least 2000 hours of cumulative operation epitomising the real load profiles.

The fuel cell system should:

• be easily transported, installed and started
• sustain vibrations and low (-30°C) and high (+50°C) ambient temperature
• be able to operate with air at low ambient pressure typical for mountain regions and other extreme environmental conditions.
• be compatible with the specific requirements and norms for transport and operation under relevant harsh environment conditions .

Proposals should address the following:

• Compact and lightweight containerised contraption including the fuel cell stack and balance of plant components, which can be transported by air, road and sea;
• Storage of enough fuel to sustain its operations during the emergency state (at least two weeks);
• Easy refuelling with fast exchange of the fuel storing modules;
• Simplified plug-and-play approach to minimise the interconnection and installation time;
• Ability of operation on green hydrogen and at least one other available or easily transportable fuel;
• Fulfillment of requirements (incl. certification aspects) needed for transport;
• Modular design with stackable and lifetime prognosis and degradation interoperable 10-50 kWe single modules;
• Include State of Health analysis at least after operation;
• Relevance to the respective standards of operation and safety.

Proposals should include the development of a strategy for the installation and operation of singular fuel cell systems in a (micro)grid utilising locally existing power supply units. The fuel cell system should be equipped with effective and highly central infrastructure independent tools for digital communication and localisation. In addition to location monitoring, the monitoring of such parameters as the amount of the fuel in the tank, the potential remaining service time (calculated real-time), and electrical parameters such as power, voltage of the system connection system, and the calculated real-time amount of supplied electricity should be considered.
