Abstract
A heat exchanger may include a coolant cavity having a coolant flow path configured for fluidly communicating coolant and a hydrogen cavity having a hydrogen flow path configured for fluidly communicating hydrogen. The hydrogen cavity may include a plurality of fins dispersed in-line throughout. The heat exchanger may further include a housing configured for thermally coupling the coolant cavity with the hydrogen cavity, optionally with the thermal coupling providing conductive heat transfer between the coolant and the hydrogen based at least in part on a portion of the heat transfer occurring through the fins.
