Systems and methods for liquid heating balance of plant components of a fuel cell module
The present disclosure relates to systems and methods for heating a fuel cell module.
1 . A system for heating a fuel cell module, comprising:
the fuel cell module having at least one inlet and at least one outlet;
an endplate;
one or more balance of plant components coupled to the endplate;
at least one channel running through the fuel cell module, the at least one channel being in fluid communication with the at least one inlet and the at least one outlet to flow a liquid therethrough, the at least one channel being formed to include a circumferential loop configured to surround a perimeter of at least one of the one or more balance of plant components located adjacent to the at least one channel; and
a heating element in communication with the at least one channel to heat the liquid flowing through the at least one channel, the heated liquid configured to heat the one or more balance of plant components as the heated liquid flows through the at least one channel.
2 . The system of claim 1 , wherein the one or more balance of plant components are formed on an external surface of the endplate, and the at least one channel is formed along an opposite, internal surface of the endplate.
3 . The system of claim 2 , wherein the at least one channel is positioned such that a region of the internal surface of the endplate adjacent to the at least one channel is opposite of a region of the external surface of the endplate along which the balance of plant components are formed.
4 . The system of claim 1 , wherein the one or more balance of plant components are mounted or integratedly attached to the endplate.
5 . The system of claim 1 , wherein an orientation of the at least one channel depends on a location of the one or more balance of plant components mounted on the endplate.
6 . The system of claim 1 , wherein the at least one channel has a diameter ranging from about 5 millimeters to about 15 millimeters.
7 . The system of claim 2 , wherein the at least one channel is etched into the internal surface of the endplate.
8 . The system of claim 1 , wherein the heating element is internally disposed within the fuel cell module.
9 . The system of claim 1 , wherein the fuel cell module is devoid of heating pads.
10 . The system of claim 1 , wherein the heating element is disposed in, around, or along the at least one channel.
11 . The system of claim 1 , wherein the at least one channel terminates in an opening that is in fluid communication with the one or more balance of plant components.
12 . A method of heating a fuel cell module, the method comprising:
flowing a fluid through one or more channels in a fuel cell module to change a temperature of one or more balance of plant components of the fuel cell module to a first temperature;
heating the fluid to a second temperature via a heating element in communication with the one or more channels, the second temperature being higher than the first temperature; and
selectively flowing the fluid at the second temperature through the one or more channels to raise the temperature of the one or more balance of plant components of the fuel cell module to the second temperature,
wherein the one or more balance of plant components is coupled to an endplate, and wherein the one or more channels is formed to include a circumferential loop configured to surround a perimeter of at least one of the one or more balance of plant components located adjacent to the one or more channels.
13 . The method of claim 12 , wherein flowing the fluid through the one or more channels further comprises routing the fluid to a location adjacent to an outer surface of the one or more balance of plant components.
14 . The method of claim 12 , wherein the one or more channels are internally disposed within the fuel cell module.
15 . The method of claim 12 , wherein the one or more channels are disposed adjacent to the endplate of the fuel cell module to which the balance of plant components are coupled.
16 . The method of claim 12 , wherein heating the fluid to the second temperature further comprises activating the heating element disposed within the fuel cell module to heat the fluid.
17 . The method of claim 12 , wherein the fuel cell module is devoid of heating pads.
18 . The method of claim 12 , further comprising diverting the fluid at the second temperature through channels of the one or more channels to bring the one or more balance of plant components adjacent to said channels to a desired temperature.
19 . The method of claim 18 , wherein the fluid is diverted independent of a location of the heating element used to heat the fluid.
20 . The system of claim 1 , wherein the one or more balance of plant components includes a hydrogen recirculation pump.
