Fuel cell with folded proton exchange membrane forming diffusion layer seal
A fuel cell ( 40 ) has a proton exchange membrane ( 41 ) having a rectangular central portion ( 42 ) and flaps ( 43 - 46 ) extending from the central portion. The flaps are wrapped around the cathode and anode substrates ( 14, 26 ) to provide respective edge seals therefor. A liquified adhesive adhe...

| Zusammenfassung: | A fuel cell (
40
) has a proton exchange membrane (
41
) having a rectangular central portion (
42
) and flaps (
43
-
46
) extending from the central portion. The flaps are wrapped around the cathode and anode substrates (
14, 26
) to provide respective edge seals therefor. A liquified adhesive adheres the flaps to the substrates and intervening filler material (
33
) so as to form a unitized electrode assembly. |
