Abstract
In some examples, a fuel cell comprising a cathode; an electrolyte; and an anode separated from the cathode by the electrolyte. The active, as-reduced anode includes Ni, La, Sr, Mn, and O, where the reduced anode includes a Ni phase constitution and a (La1-xSrx)n+1MnnO3n+1 compound having a Mn-based Ruddlesden-Popper (R-P) phase constitution, wherein n is greater than zero, and wherein the anode, cathode, and electrolyte are configured to form an electrochemical cell.
Claims23
A fuel cell comprising:
- a cathode;
- an electrolyte;
- and
- a reduced anode separated from the cathode by the electrolyte, wherein the reduced anode includes a Ni phase constitution and a (La1-xSrx)n+1MnnO3n+1 compound having a Mn-based Ruddlesden-Popper (R-P) phase constitution, wherein n is equal to or greater than one, and wherein the anode, cathode, and electrolyte are configured to form an electrochemical cell.
A method comprising forming a fuel cell, the fuel cell including:
- a cathode;
- an electrolyte;
- and
- a reduced anode separated from the cathode by the electrolyte, wherein the reduced anode includes a Ni phase constitution and a (La1-xSrx)n+1MnnO3n+1 compound having a Mn-based Ruddlesden-Popper (R-P) phase constitution, wherein n is equal to or greater than one, and wherein the anode, cathode, and electrolyte are configured to form an electrochemical cell.
A method of forming a fuel cell, the method comprising forming an electrolyte on adjacent an as-processed anode, wherein the electrolyte separates the as-processed anode from a cathode, wherein the as-processed anode includes (La1-xSrx)(MnyNi1-y)O3 or mixtures of (La1-xSrx)(MnyNi1-y)O3 plus an ionic phase, and wherein the anode, cathode, and electrolyte are configured to form an electrochemical cell.
