Description
[数1] CH3OH+H2O→CO2+6H++6e−
という酸化反応が生じ、カソードにおいては、
[数2] 1/2O2+6H++6e−→3H2O
という還元反応が生じる。これによりアノードとカソードとの間に電流が流れることになる。
高分子電解質膜111として、縦200mm、横200mm、厚さ125μmのパーフルオロカーボンスルホン酸からなる高分子電解質膜(米国DuPont社製のNafion(商品名,登録商標))を用い、
アノード触媒層112として、縦146mm、横128mm、厚さ40μmの白金・ルテニウム触媒(田中貴金属社製TEC66E50,白金・ルテニウム担持量50重量%)を用い、
カソード触媒層113として、縦146mm、横128mm、厚さ20μmの白金触媒(田中貴金属社製TEC10E70TPM,白金担持量70重量%)を用い、
アノードガス拡散層114及びカソードガス拡散層115として、縦146mm、横128mm、厚さ235μmの黒鉛繊維不織布(MFCテクノロジー社製カーボンファイバペーパSIGRACET GDL25BC)を用い、
第1補強層116A,116Bとして、外縁の縦210mm、外縁の横210mm、内縁の縦150mm、内縁の横132mm、厚さ25μmのポリエチレンナフタレートフィルム(帝人デュポンフィルム社製テオネックス)を用い
第2補強層117A,117Bとして、外縁の縦210mm、外縁の横210mm、内縁の縦142mm、内縁の横124mm、厚さ25μmのポリエチレンナフタレートフィルム(帝人デュポンフィルム社製テオネックス)を用いた。
実施例1の比較例として、実施例1の第1補強層116A,116B及び第2補強層117A,117Bを省略したこと以外は実施例1と同じ条件で膜電極接合体11を作製し、同じ評価を行った。この結果、出力密度は86mW/cm2、耐折回数は768回であった。
実施例1及び比較例1の結果から、補強層116A,116B,117A,117Bを省略した比較例1の出力密度は、実施例1の110mW/cm2に比べて86mW/cm2と著しく低い。比較例1の膜電極接合体11を目視で観察したところ触媒層112,113とガス拡散層114,115が最大で1mmずれていたが、これが主たる原因であると推察される。これに対して実施例1の膜電極接合体11については触媒層112,113とガス拡散層114,115のずれは観察されなかった。
