The first metallic plate includes a flow field, a first periphery region, a first header opening, a first side comprising a first protrusion surrounding the first header opening and fluidly coupling the first header opening with the flow field, and a second side. The second metallic plate includes an open region corresponding to the flow field of the first metallic plate, a second periphery region, a second header opening, a first side comprising a second protrusion surrounding the second header opening and fluidly coupling the second header opening with the open region, and a second side. The second side of the second metallic plate is attached to the second side of the first metallic plate using at least one of welding, adhesive, or brazing.",
