Description
本発明者らは、特許文献1に開示された従来の固体電解質層積層体(膜電極接合体)に関して鋭意検討を行った。その結果、以下の知見を得た。すなわち、本発明者らは、膜電極接合体を電気化学デバイスに用いるに際して、特許文献1に開示された膜電極接合体よりも、高い発電効率を得ることができる膜電極接合体を見出した。
本開示の実施の形態1に係る膜電極接合体10について、図1を参照して説明する。図1は、本開示の実施の形態1に係る膜電極接合体10の構成を模式的に示す図である。膜電極接合体10は、電気化学デバイスを構成するために用いられる部材であり、図1に示すように、電極11と、第1の固体電解質膜12とを備え、電極11と第1の固体電解質膜12とが接した構造となっている。換言すると、膜電極接合体10は、第1の固体電解質膜12の一方の側面側で電極11と接しており、両者を積層させた構造となっている。
本開示の実施の形態2に係る膜電極接合体20について、図2を参照して説明する。図2は、本開示の実施の形態2に係る膜電極接合体20の構成を模式的に示す図である。膜電極接合体20は、電極11と、第1の固体電解質膜12と、第2の固体電解質膜13とを備え、電極11、第1の固体電解質膜12、第2の固体電解質膜13の順に積層された構造となっている。換言すると、第1の固体電解質膜12は、その一方側の面で電極11と接し、該一方側の面とは反対側となる他方側の面において第2の固体電解質膜13と接する構成となっている。つまり、実施の形態2に係る膜電極接合体20は、実施の形態1に係る膜電極接合体10の構成と比較して、さらに第2の固体電解質膜13を備えた構成である。
本開示の実施の形態3に係る膜電極接合体30について、図3および図4を用いて説明する。図3は、本開示の実施の形態3に係る膜電極接合体30の構成の一例を模式的に示す図である。図4は、本開示の実施の形態3に係る膜電極接合体40の構成の他例を模式的に示す図である。
