Abstract
Description
以下、図1〜図7を参照して、第1実施形態について説明する。
図1に示すように、固体高分子形燃料電池(以下、燃料電池)は、膜電極接合体96と、膜電極接合体96を挟む一対のセパレータ91,92とを有するセル90が複数積層されることによって構成されるスタックを備えている。
図1に示すように、第2セパレータ92の基材は、フラットセパレータ93と、フラットセパレータ93と膜電極接合体96との間に介在された多孔性流路板94とによって構成されている。フラットセパレータ93及び多孔性流路板94はチタン板によって形成されている。また、多孔性流路板94は例えばラスカットメタルによって形成されている。多孔性流路板94には、多数の貫通孔941が形成されており、これらの貫通孔941によって酸化剤ガスの流路95が形成される。
図3(A)及び図3(B)に示すように、塗膜形成装置10は、下型20と、下型20の外周部に固設され、上方に向けて延びる複数の案内柱11と、下型20の上方に位置し、案内柱11により上下方向に移動可能に案内される上型30とを備えている。
次に、熱転写用フィルム60について説明する。
図6(A)に示すように、まずは、同図の矢印にて示す方向にベースフィルム61を搬送するとともに、ベースフィルム61の上面に対して、塗工機(図示略)の塗工ヘッド81から第1塗料63Aを塗布する。第1塗料63Aには、第1結合材631及びグラファイト粒子632の他に溶剤が含まれ、これらが均一に混合されている。なお、溶剤は例えばN−メチル−2−ピロリドン(NMP)である。
次に、基材50の表面に塗膜62を熱転写する手順について説明する。
図3(A)に示すように、熱転写に際しては、まず、上型30の加圧面が下型20の加圧面から上方に離間しており、支持部材27の支持面271がこれらの加圧面の間に位置している状態において、支持部材27の支持面271上に、一対の熱転写用フィルム60及び基材50を載置する。このとき、一対の熱転写用フィルム60及び基材50は、下型20の加圧面及び上型30の加圧面の双方からそれぞれ離間した位置において支持部材27によって支持される。
次に、本実施形態の作用について説明する。
(1)塗膜形成装置10を構成する下型20の加圧面及び上型30の加圧面の双方が、耐熱性の弾性部材40によって形成されている。このため、弾性部材40の弾性変形によって下型20及び上型30の加圧面が基材50の表面及び裏面の各突条51の頂面にそれぞれ追従し、各突条51の頂面のうち熱転写用フィルム60が圧接されない部位を少なくすることができる。したがって、基材50に対して塗膜62を適切に熱転写することができる。よって、第1セパレータ91の接触抵抗を低減することができる。
こうした構成によれば、加圧面に沿った方向へのゴムシート41の伸びが規制部材42によって規制されるため、弾性部材40によって基材50が挟圧された際に、加圧面が基材50の各突条51の頂面に追従するようにゴムシート41が効果的に弾性変形する。このため、突条51の頂面のうち熱転写用フィルム60が圧接されない部位を少なくすることが容易にできる。
(5)塗膜形成装置10は、下型20の加圧面と上型30の加圧面とが離間しているときに、基材50及び熱転写用フィルム60をこれら加圧面の双方から離間した状態で支持する支持部材27を備えている。
(6)下型20には、支持部材27を上方に向けて付勢するばね28が設けられている。
以下、図8〜図11を参照して、第2実施形態について説明する。
第2実施形態では、図8に示すように、第2セパレータ92の基材を構成する多孔性流路板94における膜電極接合体96に当接する面(同図の上面)に、耐腐食性及び電導性を有する塗膜62が熱転写により形成されている。この塗膜62の構成は、第1実施形態の塗膜62と同一であり、第1層63及び第2層64を有している。
図9に示すように、同図の矢印にて示す方向にフラットセパレータ93を搬送するとともに、フラットセパレータ93の上面に対して、塗工機(図示略)の塗工ヘッド83を通じて第3塗料65Aを塗布する。これにより、第3結合材65の層が形成される。第3塗料65Aには、上述したエポキシ樹脂の他に溶剤が含まれ、均一に混合されている。なお、溶剤は例えばメチルエチルケトン(MEK)である。
図10及び図11に示すように、塗膜形成装置10の支持部材27の支持面271上に、第3結合材65が形成されたフラットセパレータ93、多孔性流路板94、熱転写用フィルム60を同順にて載置する。第2実施形態の塗膜形成装置10は、第1実施形態の塗膜形成装置10と同一の構成である。
以上説明した本実施形態に係る燃料電池用セパレータの塗膜形成装置及び燃料電池セパレータによれば、第1実施形態の効果(1)〜(6)に加えて、新たに以下に示す効果が得られる。
なお、上記実施形態は、例えば以下のように変更することもできる。
・第1実施形態において、下型20及び上型30が、基材50及び熱転写用フィルム60が載置される前に予め加熱されていてもよい。また、第2実施形態においても同様である。
・図1に示す多孔性流路板94の少なくとも一方の面に対して塗膜62を形成することもできる。
・図12に示すように、ローラ71,72を用いた搬送装置70によって下型20の加圧面と上型30の加圧面との間に熱転写用フィルム260を搬送するようにしてもよい。すなわち、搬送装置70は、帯状の熱転写用フィルム260が巻かれたローラ71と、熱転写用フィルム260を巻き取るローラ72とを備えており、これらローラ71,72は図示しないモータによって回転駆動される。この場合、熱転写用フィルム260のうち熱転写に供された部分を下型20の加圧面と上型30の加圧面との間から自動的に送り出すことが可能となるため、下型20の加圧面上に熱転写用フィルムを載置するなどの手間を省略することができる。なお、図12は、図3(A)の12−12線に沿った断面構造に対応した構造を示している。また、同図においては、支持部材27の図示を省略している。
・ガラス繊維以外の繊維材料、例えばアラミド繊維などの耐熱性の合成繊維や、炭素繊維によって規制部材42を形成することもできる。
