Abstract
A four-fluid bipolar plate for a fuel cell includes an oxidant flow field, a fuel reactant flow field, a dedicated coolant passage, and a water management flow field. The bipolar plate includes at least one porous layer. A first side of the porous layer is fluidly connected to the water management flow field via a plurality of pores that act as a bubble barrier. An opposing second side of the porous layer includes either the fuel reactant flow field or the oxidant flow field. In one example, the dedicated coolant passage is internal to the bipolar plate, and may be configured to flow an antifreeze-type coolant.
