PEM Electrolyzer
The DISPATCHES PEM Electrolyzer Model represents a simple proton-exchange membrane electrolyzer that operates with a fixed efficiency in converting electricity to hydrogen gas. The outlet state is determined via an H2 property package.
This file here is a synopsis of the PEM system. The full description with arguments and details on the class are available in the renewable case documentation.
Degrees of Freedom
The PEM Electrolyzer Model has 0 degrees of freedom.
Model Structure
The PEM Electrolyzer Model consists of a fixed conversion rate between the inlet electricity and the outlet flow rate of hydrogen gas.
