“…The PEMFCs having planar and ducted flow field designs of ABFC with different cathode open areas and different cell orientations (45° inclined cell with cathode upward/downward, horizontal and vertical) on cathode were analysed and found that the vertical orientation of cathode flow field was the best for both designs, due to better water removal characteristics and higher mass and heat transfer [33] …”

Proton Exchange Membrane Fuel Cell (PEMFC) is majorly used for power generation without producing any emission. In PEMFC, the water generated in the cathode heavily affects the performance of fuel cell which needs better water management. The flow channel designs, dimensions, shape and size of the rib/channel, effective area of the flow channel and material properties are considered for better water management and performance enhancement of the PEMFC in addition to the inlet reactant's mass flow rate, flow directions, relative humidity, pressure and temperature. With the purpose of increasing the output energy of the fuel cell, many flow field designs are being developed continuously. In this paper, the performance of various conventional, modified, hybrid and new flow field designs of the PEMFC is studied in detail. Further the effects of channel tapering, channel bending, landing to channels width ratios, channel cross‐sections and insertion of baffles/blockages/pin‐fins/inserts are reviewed. The power density of the flow field designs, the physical parameters like active area, dimensions of channel/rib, number of channels; and the operating parameters like temperature and pressure are also tabulated.

“…Air-breathing PEM fuel cell is fuelled by methanol or hydrogen and has high current density [16]. The reason why focusing on airbreathing PEM fuel cell is that it is sensitive and highly affected by surroundings environment, such as ambient temperature, that leads the higher ambient temperature is, the higher the cell operation temperature is [17].…”

The fuel cell is a renewable technology which utilizes the hydrogen fuel via oxidation to generate electricity. The development of the technology is being focused on the most effective configurations of these processes to balance availability, efficiency and capacity. A meta-study has been conducted with the aim to analyze fuel cell performance was analysed of different materials such as; Solid Oxide fuel cells, Nafion and Peresulfuric acid under a series of variables: current density, temperature, pressure, membrane thickness and humidity. The reaction kinetics at high temperatures allow for greater hydrogen and oxygen permeability and solubility but are limited by proton conductivity of membrane at high temperature. From meta-study outcome, the largest improvement in current density is achieved by improving cathode polarity and membrane permeability. Optimizing H+ ion concentration is done by increasing humidity through increased pressure.

“…The performance of the ABFC gets affected by the type of the cathode used. Ribbed (planar) and ducted (channel) designs are the two commonly used cathode designs (Babu et al, 2016). The performance of ABFC is less compared to PEM fuel cell due to mass transportation losses and water management.…”

The world is at a cusp of major transition to fuel cell technology. Water management is of prime importance in air-breathing fuel cells (ABFCs). Inadequate water management leads to the dehydration or flooding which affects the performance of fuel cell. The paper addresses the issues of water management in ABFC by a novel method. Understanding of flooding and dehydration states is presented through experimental investigations. Experiments are conducted at various operating conditions to identify dehydration, normal or flooding states using easily measurable parameters like cell temperature, voltage and current. Preliminarily, by considering iR drop as a distinguishing parameter, dehydration and flooding operating states are distinguished.
