Server rack fuel cell

A method of accommodating differences between a rate of increase in electrical power generation by a fuel cell and a rate of increase in electrical power consumption by a computing device, the method comprising the steps of:

• detecting a droop condition by determining that the electrical power generation by the fuel cell is increasing, in response to an instruction to the fuel cell to increase its electrical power generation, less quickly than a increase in the electrical power consumption by the computing device on account of which the instruction was generated, thereby resulting in a voltage droop beyond a threshold amount in the electrical power being provided to the computing device;
• and
• performing, on the computing device, in response to the detecting the droop condition, droop-relieving actions until the droop condition is no longer detected, the droop-relieving actions comprising at least one of:
• decreasing operation of one or more cooling apparatus of the computing device, offloading processing work from the computing device to one or more other computing devices, or decreasing execution of low-priority tasks by the computing device.

A device comprising:

• one or more processors;
• and
• one or more computer-readable media comprising computer-executable instructions, which, when executed, cause the device to:
• detect a surge condition by determining that electrical power generation by a fuel cell powering the device is decreasing, in response to an instruction to the fuel cell to decrease its electrical power generation, less quickly than a decrease in the electrical power consumption by the device on account of which the instruction was generated, thereby resulting in a voltage surge beyond a threshold amount in the electrical power being provided to the device;
• and
• perform, in response to the detecting the surge condition, surge-relieving actions until the surge condition is no longer detected, the surge-relieving actions comprising at least one of:
• increasing operation of one or more cooling apparatus of the device, throttling up one or more processors of the device, requesting additional processing work to be performed by the device, or increasing execution of low-priority tasks by the device.
