Abstract
A particle filter for a fuel cell coolant is disclosed. The particle filter includes a filter housing having an upstream end for receiving the coolant and a downstream end for discharging the coolant. A filter element is provided in the filter housing. A pressure gauge is operably connected to the upstream end of the filter housing for measuring and indicating a pressure of the coolant corresponding to a degree of blockage of the filter element.

A particle filter for a fuel cell coolant, comprising:
- a filter housing having an upstream end for receiving the coolant and a downstream end for discharging the coolant;
- a filter element provided in said filter housing;
- and
- a pressure gauge operably connected to said upstream end of said filter housing for measuring and indicating a pressure of the coolant corresponding to a degree of blockage of said filter element.
A particle filter for a fuel cell coolant, comprising:
- a filter housing having an upstream housing inlet for receiving the coolant and a downstream housing outlet for discharging the coolant;
- a filter element provided in said filter housing;
- a filter inlet conduit provided in fluid communication with said housing inlet of said filter housing;
- a reverse flow conduit provided in fluid communication with said filter inlet conduit;
- and
- a pressure gauge operably connected to said reverse flow conduit for measuring and indicating a pressure of reverse flowing coolant corresponding to a degree of blockage of said filter element.
A method of removing particles from a fuel cell coolant, comprising:
- providing a fuel cell coolant filter comprising a filter housing having a housing inlet and a housing outlet and a filter element provided in said filter housing;
- distributing a fuel cell coolant through said filter housing;
- and
- determining a degree of blockage of said filter element by measuring a pressure of said coolant upstream of said filter housing corresponding to said degree of blockage of said filter element.
