Abstract
An ion exchange cartridge for a coolant system of a fuel cell stack is provided. The ion exchange cartridge includes a housing with an ion exchange resin disposed therein. The housing includes an inlet and at least one fluid-permeable outlet window configured for coolant to flow therethrough. The ion exchange cartridge is adapted to be removably disposed in the coolant system. An ion exchange cartridge assembly and a coolant tank assembly having the ion exchange cartridge are also provided.
Claims17
An ion exchange cartridge for a coolant system, comprising:
- a housing adapted to contain an ion exchange resin therein, the housing having a first end with a first opening formed therein, a second end with an inlet formed therein, and at least one fluid-permeable outlet window formed in the housing between the first end and the second end;
- and
- a closure head removably disposed in the first opening of the housing, the closure head at least partly inserted into the first opening to seal the first end of the housing, wherein the housing is configured for coolant to flow into the housing through the inlet and out of the housing through the at least one fluid-permeable outlet window, and the housing is adapted to be removably disposed in the coolant system, the closure head adapted to be coupled with a bracket for removing the ion exchange cartridge from the coolant system.
An ion exchange cartridge assembly for a coolant system of a fuel cell stack, comprising:
- an ion exchange cartridge including a housing with an ion exchange resin disposed therein and a closure head, the housing having a first end with a first opening formed therein for removably receiving the closure head, a second end with an inlet formed therein, and at least one fluid-permeable outlet window formed in the housing between the first end and the second end, the closure head at least partly inserted into the first opening to seal the first end of the housing, wherein the housing is configured for coolant to flow into the housing through the inlet and out of the housing through the at least one fluid-permeable outlet window, and the housing is adapted to be removably disposed in the coolant system;
- and
- a bracket removably coupled to the closure head of the ion exchange cartridge, the bracket adapted for removal of the ion exchange cartridge from the coolant system.
A coolant tank assembly (CTA) of a coolant system for a fuel cell stack, comprising:
- a coolant tank having a coolant inlet and a coolant outlet, the coolant tank having an aperture formed therein;
- and
- an ion exchange cartridge assembly removably disposed in the coolant tank and in fluid communication with the coolant inlet, the ion exchange cartridge assembly including an ion exchange cartridge having a housing with an ion exchange resin disposed therein and a closure head, the housing having a first end with a first opening formed therein for removably receiving the closure head, a second end with an inlet formed therein, and at least one fluid-permeable outlet window formed in the housing between the first end and the second end, the closure head at least partly inserted into the first opening to seal the first end of the housing, wherein the housing is configured for coolant to flow into the housing through the inlet and out of the housing through the at least one fluid-permeable outlet window.
