Abstract
A method of operating an electrolyzer system includes electrolyzing water into oxygen and inlet hydrogen using a polymer electrolyte cell (PEC) module including PECs, providing the inlet hydrogen to solid oxide electrolyzer cell (SOEC) modules that each include at least one SOEC stack, providing steam to the SOEC modules, and electrolyzing the steam to generate oxygen and a main product stream containing hydrogen.
Claims20
An electrolyzer system, comprising:
- solid oxide electrolyzer cell (SOEC) modules configured to convert steam into a main product stream comprising hydrogen, each SOEC module comprising at least one SOEC stack;
- a polymer electrolyte cell (PEC) module comprising PECs and configured to generate inlet hydrogen by electrolysis of water;
- an inlet conduit configured to fluidly connect an outlet of the PEC module to inlets of the SOEC modules;
- and
- a product conduit fluidly connected to outlets of the SEOC modules and configured to collect the main product stream from the SOEC modules.
