Abstract
A method of operating an electrolyzer module includes providing a first air stream and steam into a stack of electrolyzer cells located in a hotbox and outputting a product stream containing hydrogen and steam, and an oxygen exhaust stream, providing the product stream to an internal product cooler (IPC) heat exchanger located in the hotbox to reduce the temperature of the product stream by transferring heat to the first air stream, and providing the product stream from the IPC to an external product cooler (EPC) heat exchanger located outside of the hotbox and inside of a cabinet housing the hotbox to further reduce the temperature of the product stream by transferring heat to a fluid stream.
