Abstract

Emergency backup power systems for supplying emergency backup power for communication in a fully discharged fuel cell electric vehicle (FCEV), and methods of use, are provided. The emergency backup power system may comprise 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, the one or more water-activated fuel cells, 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.

First claim

What is claimed is:

1 . 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 location tracking system configured to determine geographic coordinates of a fuel cell electric vehicle (FCEV); and an emergency communication module, comprising a processor, configured to transmit an emergency communication message for the FCEV.

2 . The emergency backup power system of claim 1 , wherein the actuator comprises an automatic actuator configured to enable automatic opening of the activation valve.

3 . The emergency backup power system of claim 1 , wherein the actuator comprises a manual actuator configured to enable opening of the activation valve by manual means of a user.

4 . The emergency backup power system of claim 1 , wherein the location tracking system comprises a global positioning system (GPS) receiver.

5 . The emergency backup power system of claim 1 , wherein the emergency communication module is configured to generate the emergency communication message.

6 . The emergency backup power system of claim 1 , wherein the second wastewater reservoir is piped, in series, with the first wastewater reservoir.

7 . The emergency backup power system of claim 1 , wherein the one or more water-activated fuel cells comprise a bio-enzymatic fuel cell configured to be activated by wastewater from the second wastewater reservoir.

8 . The emergency backup power system of claim 1 , wherein the one or more the water-activated fuel cells are configured to power the location tacking system and the emergency communication module.

9 . The emergency backup power system of claim 1 , wherein the emergency communication module is in electronic communication with one or more communication networks.

10 . The emergency backup power system of claim 9 , wherein:
the emergency communication module is configured to transmit the emergency communication message to one or more response centers via the one or more communication networks, and the emergency communication message comprises:
the geographic coordinates of the FCEV; and
a request for assistance.

11 . The emergency backup power system of claim 1 , wherein the computing device is in electronic communication with one or more communication networks.

12 . The emergency backup power system of claim 11 , wherein:
the programming instructions are further configured to cause the processor to transmit the emergency communication message to one or more response centers via the one or more communication networks, and the emergency communication message comprises:
the geographic coordinates of the FCEV; and
a request for assistance.

13 . 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.

14 . The emergency backup power system of claim 13 , wherein the location tracking system comprises a global positioning system (GPS) receiver.

15 . The emergency backup power system of claim 13 , wherein the programming instructions are further configured to cause the processor to generate the emergency communication message.

16 . The emergency backup power system of claim 13 , wherein the second wastewater reservoir is piped, in series, with the first wastewater reservoir.

17 . The emergency backup power system of claim 13 , wherein the one or more water-activated fuel cells comprise a bio-enzymatic fuel cell configured to be activated by wastewater from the second wastewater reservoir.

18 . The emergency backup power system of claim 13 , wherein the one or more the water-activated fuel cells are configured to power the location tacking system and the emergency communication module.

19 . 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.

20 . The method of claim 19 , wherein:
the emergency communication module is in electronic communication with one or more communication networks, and the emergency communication message comprises:
the geographic coordinates of the FCEV; and
a request for assistance, and
further comprising, transmitting the emergency communication message to one or more response centers via the one or more communication networks, using the emergency communication module.
