“…However, pure CNTs-and/or rGO-based electrodes often suffer from a major problem that not all their Brunauer-Emmett-Teller (BET) surface area is electrochemically accessible in actual SC application. [ 127 ] Therefore, their energy densities are relatively low, as shown in Table 2 and 3 . The enhancement of their energy density should be considered.…”

Supercapacitors (SCs), also called electrochemical capacitors, often show high power density, excellent charge/discharge rates, and long cycle life. The recent development of flexible and wearable electronic devices requires that their power sources be sufficiently compact and flexible to match these electronic components. Therefore, flexible SCs have attracted much attention to power current advanced electronics that can be flexible and wearable. In the past several years, many different strategies have been developed to programmably construct different nanocarbon materials into bendable electrode architectures. Furthermore, flexible SC devices with simplified configurations have also been designed based on these nanocarbon‐based architectures. Here, recent developments in the programmable assembly of bendable architectures based on nanocarbon materials are presented. Additionally, the design of flexible nanocarbon‐based SC devices with various configurations is highlighted. The progress made recently paves the way for further development of nanocarbon architectures and corresponding flexible SC devices. Future development and prospects in this area are also analyzed.

“…This module consists of a stack of 47 cells in series. The voltage output of each cell varies between 1 V, in open circuit, and 0.6 V, at full load [9], and so, the output voltage of the module is non-regulated, varying from 42 V without load to approximately 28 V at full load. The operating temperature reaches 65°C at full load, and the module achieves normal operation within 28 s, when the parasitic loads are transferred by the Nexa control board from the external battery to the fuel cell [16].…”

Performance Analysis of PEM Fuel Cells with Different Electrical Loads

One of the most outstanding products of fuel cells is electrical power but, currently, there is a reduced number of publications that provide experimental data about the performance of fuel cells when used for supplying Alternating Current (AC) loads. Most of the existing publications provide experimental data only with direct current (DC) loads, or analyze the performance with AC loads using simulation models. For this reason, this paper analyses experimentally the behavior of a proton exchange membrane fuel cell (PEMFC) system when feeding different electrical loads. The system tested is constituted by a PEM fuel cell, a storage battery, electronic converters and electrical loads. In the tests, the fuel cell system supplies power to three different loads: DC, single‐phase AC and three‐phase AC. For these cases, voltage, current, power, power factor and efficiency data are shown, at different load levels. From those parameters, efficiency of the global system is estimated. Finally, as the power quality concept is a topic of increasing importance when supplying electricity, the total harmonic distortion (THD) of the electric signals has also been analyzed.

“…However, the major problem of pure CNTs-and/or rGO-based electrodes is that not all their BET surface area is electrochemically accessible when in contact with electrolyte. [5] As a result, their energy density is relatively low. To improve their energy density, the pseudo-capacitance from CP, such as PANI or PPy, and MOs is often coupled with the EDLC to enhance the overall capacitance of the electrode materials.…”

“…However, the major problem of high SSA carbon is that not all the BET surface area is electrochemically accessible when in contact with electrolyte, such that the gravimetric capacitance of various carbon materials does not increase linearly with the SSA, resulting in a low energy density. [5] To improve their energy density, the pseudo-capacitance from quick and reversible faradic reactions such as electrosorption or from the oxidationreduction of electroactive materials is often coupled with the EDLC to enhance the overall capacitance of the electrode materials. Conductive polymers (CP), such as polypyrrole (PPy) or polyaniline (PANI), and metal oxides (MOs), are the most commonly studied species which provide pseudo-capacitance when combined with a carbon support material.…”

As energy storage devices, Supercapacitors (SCs), also known as electrochemical capacitors, possess high power densities, excellent reversibility and long cycle life. SCs could be applied to diverse fields including electric vehicles, pulse power applications and portable devices. Flexible SCs have attracted significant attention for powering recently developed portable, flexible and wearable electronics. During the past several years, a variety of bendable carbon-based electrode architechtures and flexible SC devices with different designs have been successfully prepared. In this review, we will describe recent developments in the preparation of such bendable carbon-based electrode architechtures and the subsequent design of flexible SC devices. Future development and prospects of flexible SCs are also discussed.
