Systems and methods for processing hydrogen

A system comprising:

• (a) an ammonia reformer configured to convert ammonia into a first stream comprising nitrogen and hydrogen;
• (b) a fuel cell in fluid communication with the ammonia reformer, wherein the fuel cell comprises:
• i. an electrochemical circuit comprising an anode, a cathode, and an electrolyte between the anode and the cathode;
• ii. a channel in fluid communication with the anode, wherein the channel comprises an inlet configured to receive the first stream comprising nitrogen and hydrogen, wherein the channel further comprises one or more features which comprise (i) one or more cuts, (ii) one or more cutouts, (iii) one or more grooves, or (iv) any combination thereof;
• and
• (c) a controller comprising at least one processor configured to perform executable instructions, wherein the executable instructions are configured to:
• i. use the ammonia reformer to generate the first stream comprising hydrogen and nitrogen;
• ii. direct a second stream comprising oxygen to the cathode;
• and
• iii. direct the first stream through the channel to the anode to react the hydrogen with the oxygen, thereby generating electricity.
