ผลของภาระที่ไม่คงตัวต่อประสิทธิภาพของระบบเซลล์เชื้อเพลิงชนิด PEM

วิทยานิพนธ์ฉบับนี้ศึกษาถึงประสิทธิภาพของระบบเซลล์เชื้อเพลิงชนิดเมมเบรนแลกเปลี่ยนโปรตอนภายใต้การทำงานในสภาวะคงตัวและไม่คงตัว เพื่อระบุถึงต้นเหตุหลักที่ส่งผลต่อประสิทธิภาพของระบบเซลล์เชื้อเพลิงทั้งในสภาวะคงตัวและไม่คงตัว พร้อมระบุแนวทางการออกแบบระบบเสริมได้แก่ คอมเพรสเซอร์และชุดพัดลมระบายอากาศ การศึกษานี้นำเสนออัตราการเปลี่ยนแปลงกำลังไฟฟ้าในรูปตัวแปรไร้มิ

H2GIGA_PEP-IN - Industrialisierung PEM-Elektrolyse-Produktion - Serienproduktion PEM

Um Anlagen zur Wasserstofferzeugung zukünftig in großen Stückzahlen herstellen zu können, sind neue Produktionstechnologien insbesondere für Elektrolyse-Stacks erforderlich. Durch den hohen manuellen Anteil bei den heutigen Prozessen, der u. a. hohe Ausschussquoten zur Folge hat, sind die Herstellungskosten unwirtschaftlich.

PEM Fuel Cells

2006
PEM fuel cells use a proton conductive polymer membrane as electrolyte. PEM stands for Polymer Electrolyte Membrane or Proton Exchange Membrane. Sometimes they are also called polymer membrane fuel cells, or just membrane fuel cells. This technology has drawn the most attention because of its simplicity, viability, quick start-up, and it has been ...

PEM Effect in Germanium

Japanese Journal of Applied Physics, 1964
The PEM effect in germanium was observed by using two specimens G 1 and G 2, 7×1012 cm-3 and 8×1012 cm-3 in impurity concentration and nearly equal in their surface characteristics. The variation of the PEM voltage with magnetic field showed that the linearity held for the small magnetic field, but it saturated ...
