- Operation on infrastructure hydrocarbon – and hydrogen – fuels
- Efficient generation of heat and power
- Quiet, low emission operation
- Scalable from small light-weight, portable (e.g. battery chargers) to combined heat and power generators
- Manufacturing costs and market performance indicators
Significant progress was made over 20 years to steadily improve the key performance indicators (KPIs) for fuel cells: lifetimes, energy density and costs.
