1Power
If standard stationary fuel cell solutions are used for data center backup power, then power generation capability is provided, but capital expenditure and footprint increase compared to diesel generators
Solution Approach 1:
The patent combines the fuel cell power generation system with the data center's existing cooling infrastructure by integrating the fuel cell cooling system with the data center cooling system. This merging allows the fuel cells to utilize the data center's cooling capacity, eliminating the need for separate fuel cell cooling equipment and reducing overall footprint. The integration enables space-efficient deployment by sharing common infrastructure between power generation and cooling functions.
2Power
If standard stationary fuel cell solutions are used for data center backup power, then power generation capability is provided, but capital expenditure increases compared to diesel generators
Solution Approach 1:
The patent implements multi-functionality by designing the fuel cell system to serve multiple purposes: power generation for data center operations and power generation during backup scenarios. The system is configured to provide both primary and backup power capabilities, maximizing utilization of the fuel cell infrastructure and reducing capital expenditure by eliminating the need for separate dedicated backup power systems.
Solution Approach 2:
The integration of fuel cell cooling with data center cooling systems reduces capital expenditure by sharing infrastructure. The combined system eliminates redundant cooling equipment for the fuel cells, reducing overall capital investment while maintaining full power generation capability.
3Power
If standard stationary fuel cell solutions are used for data center backup power, then power generation capability is provided, but fuel volume requirements increase compared to diesel generators
Solution Approach 1:
The patent employs parameter changes by utilizing hydrogen fuel with higher energy density compared to diesel. By changing the fuel type parameter from diesel to hydrogen, the system achieves the same power generation capability with reduced fuel volume requirements. The high energy density of hydrogen allows for more compact fuel storage while maintaining adequate runtime for backup power scenarios.
