Abstract
Description
当業者なら、図内の要素は、話を簡単にし図を見やすくするように示されており、必ずしも原寸に比例して示されていないことを理解する。たとえば、図内のいくつかの要素の寸法は、本発明の実施形態の理解を深める助けとなるように、他の要素に対して誇張されている可能性がある。
本発明について、例を介してさらに述べる。本発明は、その例によって限定されないことを理解されたい。
(比較例)
いくつかのステンレス鋼板が、陰極洗浄され、自然に発生する不動態化酸化物および絶縁酸化物があればそれを除去する。次いで、それらの板は、米国特許第6372376号に開示されているものなど導電ポリマーコーティングで被覆される。これらの板は、導電ポリマーコーティングに隣接するチタン層を有していない。次いで、これらの板は、pH=3の模擬燃料電池溶液内で、90℃で12週間、浸漬される。これらの板は、テープ接着試験(ASTM D3359番)に従って、模擬燃料電池溶液内で12週間の浸漬後、著しい剥離故障を示す。
