Abstract
Description
特に、一般的な固体高分子電解質膜は、軟化温度(ガラス転移温度より30度以上50度以下程度低い温度とする。)以上に加熱した場合、伸びが非常に大きくなる。予備加熱機構を備える製造装置の場合、予備加熱時に固体高分子電解質膜と触媒層担持基材が伸張し、伸張率の差によって製造した膜―電極接合体に皺が発生することが確認されている。膜-電極接合体に皺が入ることは、その後の製造工程に悪影響を与え、膜-電極接合体の品質を低下させる。
さらに、接合部材から転写基材を剥離する前に、接合部材の温度調整をすることにより、熱圧着後に接合部材が外気によって冷却されても、膜-電極接合体に皺が形成されることを防ぐとともに、固体高分子電解質膜と触媒層の接着強度を高めて、転写基材を剥離する際に固体高分子電解質膜から触媒層が剥離するのを防止できる。
次に、本発明の一実施形態を説明する。なお、本発明の実施形態は、以下に記す実施形態に限定されるものではなく、当業者の知識に基づいて設計の変更などの変形を加えることも可能であり、そのような変形が加えられた実施形態も本発明の実施形態の範囲に含まれるものである。
図1は、本発明の第一の実施形態の膜-電極接合体製造装置20を説明するための概略図である。膜-電極接合体製造装置20は、固体高分子電解質膜10を巻き出す巻き出しローラー22と、巻き出された固体高分子電解質膜10の張力を除去する一対の張力除去ローラー24と、触媒層を一面に担持する触媒層担持基材12を巻き出す巻き出しローラー26と、固体高分子電解質膜10とこの固体高分子電解質膜10と接触する触媒層担持基材12とを接触させた状態で予備加熱する予備加熱ヒーター28と、固体高分子電解質膜10と触媒層担持基材12とを加熱及び加圧して接合部材14とする一対の熱圧着ローラー30と、接合部材14を温度調整する温度調整ヒーター44と、接合部材14から転写基材16を剥離する剥離ローラー36と、転写基材16の剥離角度を設定する剥離角度設定ローラー38と、転写基材16を巻き取る巻き取りローラー42と、転写基材16が剥離されてなる膜-電極接合体18を巻き取る巻き取りローラー40とを備える。
以下、固体高分子電解質膜10及び触媒層担持基材12を構成する材料の具体例を挙げるが、本発明はこれらに限定されない。
固体高分子電解質膜10の厚みは、10μm以上300μm以下程度に形成される。
また、触媒層50を構成する触媒としては、白金、パラジウム、ルテニウム、イリジウム、ロジウム、オスミウムの白金族元素のほか、鉄、鉛、銅、クロム、コバルト、ニッケル、マンガン、バナジウム、モリブデン、ガリウム、アルミニウムなどの金属若しくは白金とこれらの合金、又はこれらの酸化物、複酸化物などを用いることができる。その中でも、白金や白金合金がより好ましい。また、触媒の粒径は、大きすぎると触媒の活性が低下し、小さすぎると触媒の安定性が低下するため、0.5nm以上20nm以下が好ましい。
また、触媒層50を構成する粉末カーボンとしては、微粒子状で導電性を有し、触媒に侵さないものであれば特に限定されない。具体的には、カーボンブラックやグラファイト、黒鉛、活性炭、カーボンファイバー、カーボンナノチューブ、フラーレンなどを用いることができる。粉末カーボンの粒径は、触媒より小さい10nm以上100nm以下程度が好適に用いられる。
次に、本実施形態の膜-電極接合体製造装置20により膜-電極接合体18が製造される各工程について説明する。
図4は、膜-電極接合体18の製造の工程を例示する第一の実施形態の製造工程図である。また、図5は、膜-電極接合体18の製造の工程を例示する第二の実施形態の製造工程図である。膜-電極接合体18の製造は、まず、巻き出しローラー22から巻き出された固体高分子電解質膜10及び巻き出しローラー26から巻き出された触媒層担持基材12を張力除去ローラー24により接触させ、かつ張力を除去する。張力除去された固体高分子電解質膜10と触媒層担持基材12を接触させた状態で、予備加熱ヒーター27により予備加熱される(工程S10)。この予備加熱は、この予備加熱は、60度以上120度以下の範囲内で設定された温度によって行われる。また、工程S10の予備加熱を、以下、予備加熱工程又は予備加熱工程1とも記す。
特に、予備加熱ヒーター27によって固体高分子電解質膜10の軟化温度以下まで予備加熱し、仮圧着ローラー29によって仮圧着することにより、固体高分子電解質膜10と触媒層担持基材12とを皺がない接合部材前駆体13に加工することができる。さらに、接合部材前駆体13を予備加熱ヒーター28によって固体高分子電解質膜10のガラス転移温度以上、熱分解温度以下まで昇温し、熱圧着ローラー30で圧着することで、固体高分子電解質膜10と触媒層50の接着が強い接合部材14を作製することができる。
特に、触媒層担持基材12を温度調整ヒーター44により熱圧着ローラー30から20度低く温度調整した後に、接合部材14からの転写基材16の剥離を行うことで、外気等による冷却によって生じる膜電極接合体18の皺を防ぐことができる。
さらに、本発明の効果をより発現させるために、これらの構成に、接合部材14を温度調整する温度調整手段(例えば、温度調整ヒーター44がこれに相当する。)、接合部材前駆体13を形成する第1の熱圧着手段(例えば、仮圧着ローラー29がこれに相当する。)、接合部材前駆体13を予備加熱する第2の予備加熱手段(例えば、予備加熱ヒーター28がこれに相当する。)などを単独又は複数組み合わせて追加してもよい。
本実施形態である膜-電極接合体製造装置20では、固体高分子電解質膜10の一方の面に触媒層50を接合してなる膜-電極接合体18を製造するものとしたが、固体高分子電解質膜10の両面に触媒層50を接合してなる膜-電極接合体18Bを製造するものとしてもよい。
図6、7は、それぞれ第一の実施形態、第二の実施形態の膜-電極接合体製造装置20の変形例である膜-電極接合体製造装置20Bを説明するための概略図である。膜-電極接合体製造装置20Bは、図示するように、巻き出しローラー22から巻き出された固体高分子電解質膜10と二つの巻き出しローラー26A、26Bから巻き出され2枚の触媒層担持基材12A、12Bは張力除去ローラー24により接触させ、かつ張力を除去する。
