How Many Cells do I Need in my Fuel Cell? (Simple Fuel Cell Design Guide)
As with Electrolyzers on my previous post, there are many nuances in the optimal design of a Fuel Cell. The proper selection depends on the application, type of fuel cell, component selection and design (MEAs, flow fields, etc.) and a host of other factors. However, I will start with a simple tool that will help determine some general characteristics of a typical H2/Air fuel cell. Thanks to ...

A PEM fuel cell temperature controller design using a thermal equivalent circuit model
In order to control a temperature in the fuel cell system, a thermal equivalent circuit model for PEM fuel cells and its control algorithms are presented. By defining temperature as a state, the energy balance model can be established so that feedback control algorithm can be directly employed. The details of the design of the thermal equivalent circuit model and its control scheme are provided ...

An experimental investigation of a solar/wind 4 kW micro generation system and T-1000 1.2 kW PEM fuel cell
Hybrid system inclusive of renewable energy may be a key component for the solution of global warming, poor air quality, economic dependence, reducing-dwindling reserves of fossil fuels and also carbon tax in Australia. Firstly, this paper describes the experimental setup of wind/solar 4 kW micro generation system, examines the energy produced and various readings of monthly, weekly, daily and ...

The impact of national environmental policy on the global success of next-generation automobiles
In this paper, we identify the most crucial factors of the potential world market success of alternative car designs: fuel cell vehicles (FCVs), hybrid electric vehicles (HEVs), battery electric vehicles (BEVs), and conventional fuel efficient vehicles (FEVs). We assess which vehicle concept is favoured under which regulation regime. We suggest that the global success of a certain technology ...

Building Sustainable and Resilient Data Centers
The Covid-19 pandemic has made physical contact almost impossible to conduct business. People are staying home and going online to work and meet. This has puts pressure on data centers and communications infrastructure. It is vital that data centers are resilient, but also sustainable. There are two opposing forces at work. As demand grows, data centers expand and their energy use increases. But ...

A Finite Element Method analysis and optimisation of a polymer electrolyte membrane fuel cell with interdigitated flow field design
Interdigitated polymer electrolyte fuel cells are particularly attractive due to the enhanced transport rates and benefits with respect to electrode flooding. A 2D isothermal model is used to simulate the outlining processes that occur at the elemental fuel cell level. A Finite Element Method analysis is conducted to simulate the flow and current density fields for different gas channel ...

Hydrogen storage systems for automotive applications: project StorHy
Around two thirds of world's oil usage is associated with transportation with road vehicles consuming around 40%. Also, transportation accounts for around 25% of greenhouse emissions worldwide, with around 90% coming from road vehicles. This situation is further complicated by the fact that oil reserves are running out. For this reason, the automotive industry supported by relevant governing ...

Fuel Cell Voltage Monitoring Considerations
Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There are a few ...

Coming In Out of the Cold: Hybrids Put to the Test
Untitled Document Point Roberts, WA, Delta B.C.- May 25, 2004 With gas prices reaching an all time high and not much promise of an end in sight, hybrid technology is falling under the lens of some careful scrutiny these days with investors. In a recent article in MITs Technology Review, author Peter Fairley estimates though buyers would have to pay more ...
