Membrane electrode assembly production

A method for making an electrolyzer, the method comprising:

• forming a membrane electrode assembly by:
• continuously coating a first electrode material directly onto a roll of an initial first substrate to form a first electrode coating thereon;
• continuously coating a second electrode material directly onto a roll of a second substrate to form a second electrode coating thereon;
• continuously coating a membrane material onto at least one of the first electrode coating and the second electrode coating to form a membrane coating thereon;
• joining the first electrode coating, membrane coating, and second electrode coating in a stack with the membrane coating located between the first electrode coating and the second electrode coating;
• bonding a final first substrate to the first electrode coating;
• and
• locating the membrane electrode assembly between a first bipolar plate and a second bipolar plate to define water flow channels on an anode side of the membrane electrode assembly, hydrogen flow channels on a cathode side of the membrane electrode assembly, and oxygen flow channels of the membrane electrode assembly.

A device comprising:

• a battery configured to store electricity;
• and
• an electrochemical conversion cell electrically connected to the battery, wherein the electrochemical conversion cell comprises a membrane electrode assembly formed by:
• continuously coating a first electrode material directly onto a roll of an initial first substrate to form a first electrode coating thereon;
• continuously coating a second electrode material directly onto a roll of a second substrate to form a second electrode coating thereon;
• continuously coating a membrane material onto at least one of the first electrode coating and the second electrode coating to form a membrane coating thereon;
• joining the first electrode coating, membrane coating, and second electrode coating in a stack with the membrane coating located between the first electrode coating and the second electrode coating;
• and
• bonding a final first substrate to the first electrode coating.
