1. An electrolyzer module, comprising:
a cabinet;
a hotbox located in the cabinet;
a stack of electrolyzer cells located in the hotbox and configured receive a first air stream and steam, and output a product stream comprising hydrogen and steam, and an oxygen exhaust stream;
an internal product cooler (IPC) heat exchanger located in the hotbox and configured to reduce a temperature of the product stream by transferring heat to the first air stream;
an external product cooler (EPC) heat exchanger located inside of the cabinet and outside of the hotbox, and configured to further reduce the temperature of the product stream by transferring heat to a fluid stream; and
a main air blower configured to generate the first air stream.
