A recirculation pump includes an impeller, a pump motor assembly, and a heater. The pump motor assembly includes a pump housing having a pump cavity and a pump motor arranged in the pump cavity that drives the impeller, the pump housing arranged axially away from the impeller. The heater is disposed on or in the pump housing and spaced apart from the impeller. The heater is configured to increase a temperature of any portion of the fluid that leaks from the impeller into the pump cavity and resides in the pump cavity. The increase in the temperature causes the fluid that resides in the pump cavity to flow toward the impeller and exit the pump cavity.

A venting system includes a housing and an air intake manifold. The housing receives a fuel cell stack, and the air intake manifold extends along the fuel cell stack. The air intake manifold directs a flow of air to the fuel cell stack, and is disposed adjacent to and in contact with the fuel cell stack.
