Perovskite Solar Cells Face Challenges Organic-inorganic lead halide perovskite solar cells (PSCs) have excellent performance, and the power conversion efficiencies PCEs have increased from 3.8% to 25.7% in the past few years. However, perovskite solar cells generally use methylamine (MA) or formamidine (FA) as the organic cation component, which affects the stability of the device under heating, humidity and sunlight. To overcome this problem, inorganic perovskite solar cells [...]

Humidity and Moisture in PEM Fuel Cells In order for a fuel cell to function properly, the proton exchange membrane must retain moisture. If they are not fully humidified, the electrical conductivity decreases and therefore more energy is expended in the proton transport phenomenon. If it gets too dry, the membrane stops functioning as a proton transporter. Since hydrogen fuel cells consume hydrogen and oxygen to generate electricity [...]

PEM Fuel Cells Proton exchange membrane (PEM) fuel cells convert hydrogen and oxygen into water, releasing energy. At the heart of a fuel cell is a proton exchange membrane (catalyst-coated membrane, CCM) coated on both sides with a platinum-based catalyst. PEM fuel cells can be used in different mobile and stationary applications such as energy storage, forklifts, light and heavy trucks. In transportation, fuel cell electric vehicles compete [...]
