Backup power supply for emergency communication in a fully discharged fuel cell electric vehicle

An emergency backup power system, comprising:

• a first wastewater reservoir configured to store wastewater from a fuel cell state;
• a second wastewater reservoir configured to store wastewater from one or more water-activated fuel cells;
• an activation valve configured to enable water to flow from the second wastewater reservoir to the one or more water-activated fuel cells;
• an actuator configured to open the activation valve;
• a computing device, comprising a processor and a memory, configured to store programming instructions that, when executed by the processor, cause the processor to:
• determine geographic coordinates of a fuel cell electric vehicle (FCEV), using a location tracking system;
• and
• transmit an emergency communication message for the FCEV, using an emergency communication module.

A method for supplying emergency backup power for communication in a fully discharged fuel cell electric vehicle (FCEV), comprising:

• filling a second wastewater reservoir, of an emergency backup power system, with wastewater,
• wherein the emergency backup power system comprises:
• a first wastewater reservoir configured to store wastewater from a fuel cell state;
• the second wastewater reservoir configured to store wastewater from one or more water-activated fuel cells;
• an activation valve configured to enable water to flow from the second wastewater reservoir to the one or more water-activated fuel cells;
• an actuator configured to open the activation valve;
• a location tracking system configured to determine geographic coordinates of a FCEV;
• and
• an emergency communication module, comprising a processor, configured to transmit an emergency communication message for the FCEV;
• opening the activation valve, enabling water to flow from the second wastewater reservoir to the one or more water-activated fuel cells, causing the one or more water-activated fuel cells to generate power to power the location tracking system and the emergency communication module;
• determining the geographic coordinates of the FCEV, using the location tracking system;
• and
• transmitting the emergency communication message, using the emergency communication module.
